BMW 320i: 2001 model..climate control..the fan speed indicator remains

This answer was rated:

I have a BMW 320i, model e46, 2001 model. Recently I have noticed that the air distribution on the climate control seems to fluctuate for no apparent reason, but the fan speed indicator remains constant. I have had it regassed and changed the pollen filter to no avail. This also happens with air con switched off. Can you help please.

George :

Whenyou say fluctuate do you mean the fan speed is fluctuating?

Customer:

Don't think fan speed increases as the bar indicator remains steady on 3 bars, but it sounds

Customer:

as if it does increase. Fan is free rotating by hand and not binding.

George :

Can I have the last 7 digits of your VIN #

Customer:

FF17293

George :

Your problem is caused by the blower motor Final Stage Transistor pack and it will need to be replaced. This is an extremly common problem and the new part has been updated. It is item # XXXXX in the diagram below.
