FSR fault, or worse?
Just got done with the starter and battery swap on my 06 330i. I suspected the battery was the only culprit, but when the starter gave up the ghost I knew it was both lol. Anyway I had read that the blower motor can be limited if the battery is dying. My blower would only work on defrost hence my suspicion of battery. After replacing battery, programming it, then replacing starter, the blower motor wouldn't work at all. I pulled the FSU and there are scorch marks on 2 pins from the harnass. Is this "normal" for a failed FSU or should I look further before getting replacement?
