So Fix it

How to Change a 1991 BMWs Blower Motor

The blower motor on a 1991 BMW pushes the air from the air conditioning compressor and the heater core out through the vents in the dashboard, heating or cooling the interior of the vehicle. Should the blower motor fail, the climate controls will fail with it. To fix the problem, you can change out the failed blower motor for a new one, a process that should take under 30 minutes to do.

Instructions

1

Pop the hood on the BMW. Remove the weather stripping at the firewall with your hands, then cut the zip ties that hold the wiring to the motor cover with the side-cutting pliers. Unbolt the cover from the motor with the 3/8-inch ratchet and socket.

2

Unbolt the retaining straps from the blower motor with the 3/8-inch ratchet and socket. Unplug the wiring to the motor with your hands, then take off the clamp holding the blower motor in place. Pull the blower motor out of its mount.

3

Install the replacement blower motor into the mount and reengage the clamp. Plug the wiring into the blower motor and then reinstall the fan cover and the straps with the 3/8-inch ratchet and socket.

4

Reinstall the blower motor cover with the 3/8-inch ratchet and socket. Reinstall the wire across the cover with the zip ties and push the weather stripping back onto the stock area.
