Got in the car last night, and the cabin fan cranked itself to max upon startup (ACC on Auto). Thought it was odd because it was fairly cool in the car. Would not respond to the fan speed control, wouldn't even shut off (all other ACC controls work normally). Then the fan started screaming like a banshee for about 3 mins., then quit making noise but still ran. Does not shut off. I finally pulled the fuse. Put fuse back in, same problem. Am I looking at a bad fan resistor, or a bad motor, or both?

TIA,
Barry

Definite resistor, maybe both

That's what I'm thinking. I just read a Bay13 writeup that said as the motor start to go, the excessive load may smoke the resistor too.

Both - That squealing was most likely dry bearings.
Your motor started dragging and killed your power stage.
:facepalm:
Yippee!! I won the Daily Double!! :thumbdown:

Well, the motor assy doesn't look as bad in price or R&R as I had expected, at least not compared to old-skool Volvos.
They're pretty proud of the resistor, though. But it could be worse, of course. :rolleyes:
Maybe I'll :beer::beer::beer:, and tackle this one meself.

Once you get to the motor, the power stage is right there.
The harness around that stuff can get in the way and be
a little tricky, but it's not too bad.
