So Fix it

Check the fuses first by locating the fuse panel. On the Ford Taurus, you will note that there is a fuse box under the hood as well as another one under the driver-side foot well. The fuses for the electric power windows are on the underside of the foot well and near the steering column.

Unclip the panel and reveal the fuses. Take out the appropriate fuses that correspond to the power windows and check their condition. Good fuses will be clean and silver with a good connection to the circuit.

Assess the condition of the electrical switches. If all four windows are working intermittently but not fully operational for the remainder of the time, the problem could lie in the relay switch. If one window is having trouble but the other three are all working correctly, it could be the motor for that particular window. Usually the drivers window is the first to fail because it gets far more use than the others.

Remove the door panel by unclipping the plastic grommets and the screws around the door. One small screw will be located just above the door latch on the inside of the panel. Pop the panel off and locate the screw inside the door pull.

Unclip the switch cover and dislocate the relay plugs from the connectors inside the door panel. You will note that they are bundled up inside the metal door skin. Check the plug connections and replace them. If the windows still do not work, you may need to replace the motor for the window. The motor is attached to the bottom of an "X" shaped frame inside the door skin and is a small, silver and black barrel in the lower center of the frame. These are hard to remove, so you may need to take your car to a mechanic to have the motor replaced.

Make sure your Chevy Sprint is completely cool before you start troubleshooting.

Pull the hood latch and open it up. Find the radiator in front of the engine -- it has a cap on it that says "radiator."

Remove the radiator cap by flipping up the pressure release tab on the top of the cap and turning the cap counterclockwise. Set the cap to the side.

Look inside the radiator through where the cap was. Make sure that the water level is to the top. Your Sprint can overheat if there is not enough coolant in the radiator.

Start up your Sprint engine. Make sure the radiator cap is still off the radiator. Look inside the top of the radiator and watch the coolant. Let the engine warm up. When the engine is warm, the water inside the radiator should drop down and then start to circulate. If you do not see the water level change or start to circulate, it is a sign that you have an issue with your thermostat. The thermostat is located in the housing cover where the top radiator hose is connected. You can follow the top radiator directly to this housing. If the thermostat is not opening when the engine gets warm, then your Sprint engine is certain to overheat . A bad thermostat is the most common reason why a Chevrolet Sprint will overheat.

Listen for the cooling fan to come on. When the engine reaches a certain level of warmth, the electric cooling fan will come on to cool down the engine. The cooling fan is mounted on the back side of the radiator. If the fan does not come on when the engine gets warm, then your Chevy Sprint engine will overheat.

Check for coolant leaks. Look on the ground under the engine. Look at the radiator and all the hoses coming in and out of the radiator. If you see any steam or leaks, this is the cause of the overheating problem. Replace any leaking hoses or leaking parts. The cooling system must always be pressurized to work properly.

Turn the key to the ignition in the truck or SUV that your D12 is installed on. Look at the gas gauge to make sure that you have enough diesel in the tank to get your engine started. Fill the gas tank with enough fuel to start the engine.

Replace old fuel after a seasonal change. You cant use winter diesel in the summer and vice versa. Winter diesel can have condensation in it, which causes misfires to the engine.

Siphon out your old diesel to replace it with fresh fuel. Insert one end of a siphon hose to your gas tank. Insert the other end of the hose to an empty container. Pump the siphon hose until all of the gas is out of the tank. Fill the tank with the proper gas.

Jack up the front of the truck and climb underneath the engine. Have a friend turn the ignition in the truck. Listen to the small black box on the right side of the engine. This is the starter. If you hear any clicking from the starter, have a technician replace it.

Look for leaks around the D12. If you notice any leaks, you should have a mechanic take a look at your engine. Mechanics have special devices for diagnostic tests.

Turn the car and stereo off. Disconnect the left and right speakers at the amplifier. Connect the left speaker to where the right one was and the right to the left. Turn on the stereo system. If the speaker still does not, work then the problem is in between the amplifier and speaker itself.

Put the left and right speakers back to where they were in the amplifier. Make sure the car and stereo are off. Switch the position of the RCA cables in the amplifier. Put the left one where the right one is and the right one where the left one is. Turn the stereo on. If the speaker still does not work, the amplifier may be broken.

Test the crossover. The crossover will be connected to the amplifier and the head unit. Plug the RCA cables that are going into the amplifier into the extra outputs on the crossover. Turn on the stereo. If the speaker works, then you know it was the output on the crossover that was faulty.

Pull the head unit from the dashboard. This can be done by hand if the head unit is just sitting in place. You may need to have the head unit professionally removed if it is connected within the dashboard. Remove the RCA cables from the back of the head unit. Do not unplug any other wires. Put the RCA cable for the speaker that is not working in the output for another speaker. Turn on the stereo. If the speaker works, then the problem is either the RCA cable or the output on the head unit. If the speakers are still not working, then they may need to be replaced.

Put on safety glasses. Remove at least one headlight bulb, using a screwdriver to remove the hold-down ring around the headlight, and test it. Connect a jumper wire between one of the parallel prongs of the headlight and the positive terminal on a 12-volt battery. Connect a second jumper wire between the negative battery terminal or a grounded engine component and the single prong below the two parallel prongs. If the light is bad, replace it.

Inspect the entire fuse box for any blown or discolored fuses. The fuse box on a 69 Chevy truck is located under the dash on the drivers side of the truck. The 69 Chevy truck uses a glass tube fuse.

Inspect the ground wire, which bolts to the radiator support behind the headlight socket on most older vehicles, for a good connection. If the connection is burnt or discolored, unbolt it with a wrench and clean it with a wire brush. Most models have a small black wire that mounts to the chassis with a 5/16-inch self-tapping metal screw.

Charge the Chevy trucks battery with a charger or by running the engine for 15 minutes. If you are charging the battery, the red terminal of the charger should be connected to the positive terminal, and the black terminal connects to the negative terminal of the battery.

Pull the headlight switch to full-on position. If the switch is pulled out halfway, it lights the parking lights only. Click the dimmer switch several times; take notice as to whether the high-beam indicator lamp in the dash lights up. If the high-beam indicator lights up, test the dimmer switch.

Roll back the carpet or floor mat around the dimmer switch, found on the truck floor. Locate and remove the connector plug. Use two jumper wires and join all three wires of the dimmer switch plug together. If the headlights come on, replace the dimmer switch. If lights do not come on, check the plug with a 12-volt test light for a hot wire. One wire in the plug should light the test light unless the headlight switch is bad. Be sure the test light is grounded to a metal ground.

Remove the headlight switch. The main mechanism of the switch is behind the dashboard and the pull knob is on the outside of the dashboard. From under the dashboard, press the spring-loaded tab, located on the switch mechanism, and rotate the headlight switch to the left to activate the interior lights. The switch must be rotated to pull the knob and rod out of the switch mechanism. Unscrew the thin nut on the front side of the dashboard that holds the switch in the dash with a box-end wrench. Drop the switch below the dashboard and unplug it.

Probe the headlight connector plug with a 12-volt DC test light until the hot wire is found. If no hot wire is found, check the plug that comes through the cowl near the fuse box on the cowl side of the cab. Check the plug and headlight switch for heat related failure, melted or discolored wires.

Inspect the wiring harness plugs, on the firewall side of the cab, that go through the firewall, for burnt or discolored wires. These wires are located around the area where the steering shaft comes through the cowl.

Trace the wiring harness from the headlight bulbs or headlamps back to the cowl, checking for cracked, frayed or burnt wires. If any damaged wires are found, replace or repair the wiring harness.

Walk around your Tahoe and look at each tire to see if one of them looks low.

Slide the air pressure gauge over each valve stem to check each tire and make sure that it is inflated to the proper psi. The proper psi is noted on the car door. Never go by the maximum inflation noted on the tire. You must always go by what is indicated on the car door. Improper inflation will cause the TPMS unit to flag a problem.

Take your TPMS computer scanner out of the box and become familiar with the settings. You will need to push the buttons on the front to find your make and model of car. Press the button to enter the scan mode and walk around to each tire. Press the button at each tire until you get an indication that the scanner cannot find the TPMS unit. This is the unit that needs to be changed.

Park the Freightliner on a level surface. The weight of the vehicle should be evenly distributed on all of the tires. Park near an air pressure machine, such as at a truck stop or large service station.

Go to the first tire on your Freightliner that you think may have a defective pressure monitor.

Make a note of the required pressure from the label on the tire. If you do not know the required pressure, contact the manufacturer or the tire retailer.

Turn the key inside the Freightliner to the "Accessory" or similar position so the electrical system turns on. The trucks dashboard gauges need to be functioning so you can get a reading from the pressure monitor.

Locate the valve stem on the tire and remove the cap from the stem. Use a small flat-head screwdriver to press down on the tip inside the valve stem to release the air out of the tire.

Wait until the tire is about halfway flat and then check the gauges inside your truck. The pressure monitor should be lit. Replace the pressure monitor if it is not lit. Replace the air removed from the tire.

Check that the knob on the device is set to "CD."

Insert a lens-cleaning CD into your CD player. Available at most electronics stores, these CDs have small brushes on them that delicately clean the laser that reads the discs. If your CDs are skipping, this will likely solve the problem.

Replace the CD player fuse. If the fuse is dead or loose, this could be causing the problems. Use your car owners manual to locate the fuse box and check the fuse labeled "stereo."

Check the stereo connections. Again, your owners manual will tell you how to find them. If the connections are loose, adjust them. Be sure that the car is turned off when you do this! If the wire is frayed or the connections are broken entirely, you will need to take the car in to an auto shop for repair.

Open the front hood on your Montana.

Start the engine.

Remove the transmission dipstick and wipe it with the terrycloth. The dipstick is located on the side of the engine and has the word "transmission" on it. Stick the dipstick back in and then take it right back out. Look at the fluid level. Make sure that it is filled to the line indicating cold level. Low transmission fluid will cause the vehicle to shift hard and make a whining sound.

Look all around the transmission for any loose, broken or frayed wires. The transmission works by hydraulics that are controlled with electric sensors. If any of the wires are not connected, it will cause transmission malfunctions.

Smell the fluid in the transmission. You can pull out the dipstick again and make sure that the fluid is clean. Dirty and burnt-smelling fluid can cause serious issues with the Montana transmission.

Open the petcock, fully extend the choke, put the transmission in neutral and start the motorcycle. Push the choke halfway in after 30 seconds.

Allow the motorcycle to run until the rocker covers, which are the chrome boxes on top of your cylinders, are very warm to the touch. Listen for coughing.

Push the choke completely in. Twist the throttle about halfway open and release. Repeat two or three times.

Listen for coughing. If the motorcycle coughs when the choke is pushed in but not when the choke is pulled out, your motorcycle is running too lean in what mechanics call the "idle circuit" because there is too much air and not enough gasoline in your fuel-air mixture. The idle mixture screw on the bottom of your carburetor is improperly adjusted.

Examine your air cleaner cover. If your air cleaner is original equipment it will be secured with one Allen bolt in the middle of the cover and will be marked "Harley-Davidson." If the air cleaner cover is not original, your air cleaner assembly may have been replaced.

Examine your motorcycle exhaust. If your motorcycle exhaust and air cleaner are both not original equipment, your Harley 883 may need to be rejetted. The standard low speed jet on an 883 Sportster is a Number 42. You may need a Number 45 or a Number 48 low-speed jet.

Loosen the Allen bolt in the middle of your air cleaner cover with an Allen key or wrench and remove the cover. Find the spot behind the carburetor where the carburetor mates with the intake manifold.

Spray carburetor cleaner on the intake manifold while your motorcycle is running. Do not spray into the air cleaner. If the idle changes speeds while you spray carburetor cleaner only at the intake manifold, you have a leak there. You need new air intake seals.
