Intermittent Fan Blower

[Ricmundo]

Hi all hoping someone knowledgeable can help, I have been having problems with the fan in a 2011 A4. Initially it died completely, no air coming into the car and with the weather getting cold and I decided to investigate myself. When I removed the fan blower motor it was pretty grubby so I thoroughly cleaned and re-lubricated it and thought cant hurt to try it again. Lo and behold it started working again, I also removed and cleaned the blower resistor at the same time. It worked great for about 2 months but died again yesterday, strangely it seems intermittent it just comes on at random when im driving. I'm sure its either the fan blower motor or the blower resistor (suspect fan) but as I cleaned them both at the same time and put them back in I cant be sure which is the culprit. I also checked all the wiring for loose connections or damage and everything looked good so I guess has anyone experienced this before?

Thanks in Advance.

Hi Rick I believe fan issues aren't uncommon on the b8 and I believe most of the time the faults are linked back to the fan motor or the motor controller.

Hi Steve, I changed the resistor in mine tonight to no avail. Is that what you mean by motor controller or is that something else and if so what and where? Thanks, Brian
