Need Help! Problem With Blower, Heater.

[DiRay]

Problem with my 1991 325i bimmer's blower heater, works only on 4-th position on max. Anyone had this problem? As I was told, some fuses or something like that has smoked. Can anyone tell me where those fuses are? And how to change them?

needs a blower resister, its in with your blower motor, under the hood up on the fire wall

Not a fuse problem, the contacts on the resistor are dirty. Pull the access panel off of the firewall-easy to see. The resistor is under the blowere motor cover-two straps hold it on. Pull the resistor up to unplug-clean all the contacts especially the pont set in the center. try it with the cover off as you'll probably have to do it 2-3 times. easy fix. also get some contact cleaner to spray on the plug-in sockets

just replace the resister, they are cheap and then you wont have to worry about it anymore
