The blower motor in your car's air conditioner is vital to the function of the heating and cooling system. If it doesn't function, your engine may overheat. You can inspect the motor to keep it running efficiently. You'll usually find the blower motor under the instrument panel or cluster.

Things you need
- Magnetic Tray
Disconnect the blower motor connector and remove the retaining screws with a standard screwdriver. Set the screws aside on a magnetized tray.
Detach the fan retainer clip from the motor shaft, located in the center of the blower wheel. Save this piece if you're replacing only the wheel. If you replace the entire motor, a new wheel and retainer clip will be included.
Inspect the blower motor for damage, excessive corrosion or rust. Remove any debris with a air compressor. Apply engine cleaner on the solid parts of the motor to remove dust or other gunk.
Inspect each of the working parts, like the wheel, to make sure they work, or spin freely. If they don't, repeat the above steps to clean them, and then test everything again.
Tips and warnings
- Disconnect the battery and wait at least two minutes before starting. This allows time for the air bag to lose energy so it will not deploy while you are working.
