If you have auto climate control, replace the blower motor controle module.

If you have Manual climate control, replace the blower motor resistor assembly.

Both are in the same place, on the bottom of the blower motor itself. Take off the plastic kick piece at the bottom of the glovebox to access the bottom. You'll see small screws holding the piece to the blower motor. From there, empty your glovebox and open it. You'll see an access hole to the left, stick you finger in there and depress the spring loaded piece to drop the door upside down. There you'll have access to the electrical connector from the blower resistor to the blower motor. Very easy job and is a very very common thing to go bad.

Interior air fan speeds 2, 3, and 4 have quit working.


Either the fan itself is shot, or there is a vaccuum leak on the hoses in back of control switch

My air conditioner is not working on my 2002 BMW X-5. The air is cool it just won't blow out.


If there is air moving through the vents most likely the final stage transistor(blower resistor) has failed. It controls blower speed from a signal from the ihka (a/c control panel). the final stage receives the signal from the ihka of the drivers preference blower speed. the final stage pwm (pulse width modulates) the blower motor. which means it turns it off and on very quickly to speed up or slow down the blower motor speed. It isn't the easiest part to replace. Usually at a dealership i would expect to pay somewhere around $600 (including diagnosis)but don't hold me to it. bmw dealerships stand behind their repairs and usually include a warranty with the part of 2 years unlimited mileage.

Heater motor will not work on #5, it worked for 5days after resis


First check to make sure the electrical connector on your switch is o.k. if it looks burnt /brown or melted replace your switch, and the connector.If all is well then replace your blower motor, it may be drawing to much current (AMPS). Along with a new resistor block.

Fan speed switch only works on #5


Call your local GMC Dealer and see if they have the climate control panel in stock. What happens is the circuit board on the back of the panel shorts out. The panel comes as an assembly and is very easy to replace. Don't go with a wrecking yard piece. I made that mistake once and it didn't work either. I got one from the Chevy dealer and it worked perfectly.
