No heat or A/C, no air flow, need advice DIY
I have an 03 330ci with no air flow. I hear the fan motor running but there is no air in any of the vents. Oddly enough though, when I turn on the defroster I do feel the air on the windshield. I have done lots of research so I either need a new blower motor fan or a new FSU (final stage unit/resistor). Which one do you think it is? I want to fix it myself but I need to know which part to order. At first I thought the blower fan motor was broken but I can hear the fan on HIGH, and the defrost works. But NO AIR FLOW! Please Help!
