Would need more information to help with this issue. Do you mean you blower fan has stopped working or only works on one speed? Or does it no longer blow cold air with the blower is working normally?

In the E30's, dirty resistors in the firewall were the culprits. Cleaning them with electrical parts cleaner, the non- flammable version, usually did the trick. As for the E36, similar parts may have been used. It's worth a try.

Check the fuse first.

use direct current to test the blower and if it does not work, replace it. If it works you'll need to check the rest of the system.

Michael is correct you have a problem with you blower motor resistor. You will need to replace this in order to get you blower fan running agian on all speeds. You will need to take down the drivers kick panel and knee bolster. It will be towards the bulk head on the heater box. If you can't find it go to pelican.com they have a DIY instructions on how to replace it. You may still have to replace your blower motor but I would start with this first. Good luck and hope this helps.

The blower doesn't have 4 speed. The resistance makes the variable speeds. If yours is a digital a/c of course. The blower is under the right side of the dash, you will have to take some cover or the glove box to acces it. You will notice the shape of the motor when you see the a/c box.

Step 1: Insert 78% Nitrogen, 21% Oxygen, and 0.93% other gases into the passenger side, rear tire. Step 2: Please ensure the fuel lid cover is properly secured in its intended locking position. Step 3: Take a seat in the driver side seating position. THIS IS VERY IMPORTANT. Having a seat in ANY other location is not only dangerous to yourself, but also to others on the highway. Step 4: Place the vehicles ignition actuating device into the ignition located (on the steering column) or on the dash/instrument panel. This will be marked as such. Step 5: Ensure the gear selector lever is in the "P" Park position. If standard transmission is your choice, please ensure the gear selector lever is in the "N" Neutral position. Step 6: Depress the brake pedal, and clutch if applicable, and start the vehicle. Step 7: With your foot applied to the brake, select the desired gear selector lever position, usually D, or 1, and ease off of the brake pedal. Step 8: STOMP on the accelerator, and with your free hand, roll down all windows to experience the full effect of atmospheric Air Conditioning. This concludes your instructions for repairing the BMW AC. Thank you.
