My fanny...

I replaced my battery yesterday as advised by the helpful members of this site and it was all good.
However, upon connecting the new battery I noticed that my 2003 BMW 316ti's fan made the usual noise but did not appear to respond to the directional switch on the dash.
What didn't help a lot either was that the weather was too damned hot.
I reset the oil service light and the clock, but this fan problem has got me beat.
Help please.

Not at home right now but would be tempted to say your final stage resistor pack has failed. Do a search for final stage resistor and take a look to see if symptoms match yours.

Man, you're sure quick, and thanks again for the advice re my battery yesterday.
Until I get a chance to research and probably get the FSR thingy fixed, can you advise as to whether an FSR problem would cause me any troubles with the running of my car in the meantime?

Howdee, I never had my FSR fail in my eight years of ownership (no longer have car) but as I understand, no, basically the failure mode involves the fan being 'stuck' at one position.

Maybe others can chime in to help.

So how did the battery work out?

Not necessarily. A bad FSR can manifest in many ways. The blower speed fluctuating on its own, the fan working only at the highest speed etc are all symptoms,

MME30W - many thanks, as the battery seems to have done the trick re the car petering out.

Thumbs up

Thanks once more guys.
Replacing the final stage resistor as you both advised fixed my problem.
