: 91 525i blower moter

12-04-2008, 07:55 AM
The blower motor had been making a sqeal noise on lower speeds but last night it blew smoke out of the vents that seemed to smell like the blower moter burning out. But the motor worked this morning as I was moving it out of the way to get our other car. Does anyone have an idea if it's something else like a relay? Thanks for anyones help.

The squeal was probably the bearings failing. The smoke might have been the blower burning out or it could have been the blower sucking in the smell of something else burning (I had this happen when my aux water pump burned out).
The blower motors resistor or the sword is about the only other part of the blower sys that I think would generate smoke. The smoke from those parts would not be comming out of the vents. It would come from the psgr footwell area (it might work its way up under the dash).
