Fan control knob

The blower control knob on my 98 2.8 quit working today....1,2 and 3 dont turn on the blower but 4 still works. Switch issue or blower issue?

Thanks....also getting ready to remove new top to replace body seal. Dealer replaced top but not seal. Anybody near Charlotte NC with experience willing to offer wisdom?

Then seat bushings and glovebox door fix...

Loving my roadster!

Tom

Faulty blower resistor. 4 is high fan and sends battery voltage. 1 thru 3 step the voltage down through a resistor. Not sure where it is on the Z3. I'm sure someone can direct you to the correct location. Usually near the blower motor.

Blower resistor is located under the trim panel beneath the wipers with the blower motor. Once the trim panel is off it just slides out. It's not an uncommon occurrence and I know there are some writeups with pics scattered around the various bimmer sites.

Raise the hood, remove the wiper arms, remove the wiper cowl and then you'll see a round plastic cylinder covering the heater fan with 2 plastic ties on it.. remove these ties and the cover comes off exposing the heater fan and final stage resistor..

the resistor is the blue part here (your one might not be blue
