Fan Control

[scoand]

2002 325ci - I have very little manual control over the fan speed. Seems to be stuck in auto mode. No trouble codes. Does anyone have any ideas of what it may be? Thanks

Which fan mate?

Heater/cooling fan...maybe??

For inside cabin?...might be wrong though

Do the vent buttons on the heater-control not work then? (Above the "Auto" button on most BMW's)

is it the climate control unit???? is it stuck on auto???? and does it go off and on intermittently????/

It is the climate control. The fan speed goes high and low intermittently regardless of where I manually select it.

I assume you are referring to the recirc button. Yes, everything works except.I can't manually control the fan speed.

Climate Control, blower fan.

the climate controls do have a mind of their own im afraid .......... does the unit go on and off occasionally too or has it not got to that stage yet?????? there is a resistor inside that tends to go and can cause different problems with the climate control..........

Doesn't go on and off by itself.

heater resistor pack "hedgehog" will sort that out.

"Probably" will, but needs to eliminate others first... It is a common fault though !!

His 2002 model will have the updated resistor but just about anything can fail ;)
