Hi I'm having a problem with my blower not working at all. Replaced both blower and fsu. Checked the connector and did the new connector replacement. It has power and ground 13-14v, I just wanted to know if somebody can disconnect their blower motor and tell me if there is power at the small wire(signal wire I think?) when the blowers are on.

My 2009 335i blower motor quit working. I had it repaired/replaced by Foreign Auto Services in Riviera Beach. They used their diagnostic tools to determine that the problem was with corrosion internal to the Blower unit. I have heard rumors of dealer charges. Foreign Auto cost complete was $507.

I was hoping this was going to be a supercharger question...

My blower will run fine on high then suddenly change to low speed even though the control still show high speed. Blower and resistor are new so I suspect there is an issue with the signal at the resistor which I think may be digital, although not sure. Haven't really found any threads yet regarding checking the signal or a fix if the control signal is the issue.

How's the battery? The car will pull power from non essentials from time to time if it is on its last legs.

hope this helps guys https://static.nhtsa.gov/odi/rcl/201...7V676-3259.pdf
i think somewhere down there that says if you had issues and fixed it already prior to notice they will reimburse? idk how that works, but hope it helps

there was a recall for something in that area I think was a connector.

Also the resistor for these has a tendency to go bad.

Yeah, check on the recall status. That might affect it.
