Heat/AC issue

rbrtclk · 05-22-2014, 02:43 PM

I have a 2009 335ix. when I push the button to turn my climate control system on, I get no blower. I checked the fuse and it's OK. What next?

Probably blower motor, had same problem 2 weeks ago. Repair at dealer was about $1k

As odd as it sounds, try charging the battery. When the batteries get low, the cars start shutting off certain things to conserve battery life. For instance, the doors won't beep when you unlock them, etc. I have a 2011 335i and in the winter when the battery is low (I have short commutes), the blower fan is low or high...Nothing in between. I charged the battery and all the fan levels started working again.

Do you get anything on low or high? If you do then your blower motor resistor is probably out. If you get nothing at all then your blower motor could be on its way out. Give it a couple of good taps and see if it starts up.

If your defroster works but the heat/AC does not, them it is battery. It could be the final stage resister. Search for it and you will find a lot of info.
