So Fix it

Replacing the flasher relay on your Volvo 850 can be done very quickly and requires no tools. The flasher relay routes the power from the turn signal switch to the turn signals, converting the flow of electricity from a solid stream of power to an alternating stream, which causes the lights to flash on and off. If the relay fails, you can replace it with a new one, available from any auto parts store or through your Volvo dealer.

Instructions

1

Open the hood of your Volvo and locate the fuse box on the drivers side of the engine compartment up against the firewall. Open the plastic lid by releasing the locking tab on the drivers side of the box then swing the lid towards the passengers side.

2

Locate the flasher relay on the drivers end of the box, grasp it by the sides and pull it straight out. Discard the old flasher and install a new one by pushing it straight into the fuse box where the old one came out.

3

Close the lid, snapping the locking tab in place. Close the hood of the car and test the repair by turning the ignition on and activating the turn signals, one side at a time.

Turn signals are lights located at or near the exterior corners of all cars, including the Chevrolet Lumina, that signal the drivers intention to turn. The driver activates either the left or right turn signals via a switch usually found on the steering column. The turn signal lights blink, thanks to a module in the turn signal electrical circuit called a flasher. Sometimes, this flasher malfunctions or wears out. As a result, the turn signals either wont flash or wont come on at all.

Instructions

Test the flasher

1

Have an observer stand near the back of the vehicle so they can see both turn signal lights.

2

Engage the parking brake if you havent done so already.

3

Start the car.

4

Apply the brakes. If the observer sees the brake lights working correctly, proceed. If one or both brake lights dont work, you must troubleshoot the brake-turn signal circuit or refer the problem to a certified automotive technician.

5

Activate the turn signal, first in one direction then the other. If the observer doesnt see the turn signal lights flash on either side, replace the flasher.

Replace the flasher

6

Turn off the car.

7

Find the flasher. The flasher is a cylindrical module approximately 1-inch diameter by 1-inch long, plugged into a connector. The flasher is found beneath the driver side dash, near where the steering column passes through the firewall.

8

Unplug the old flasher from its socket.

9

Install the new flasher.

10

Perform the Step 1 test to ensure the new flasher works properly.
