The heater in my '90 740 GL doesn't work...aaarghh. I worked the graveyard shift last night and after the car warmed up turned the switch to get some BTU's flowing. Except I got nothing. I couldn't hear the blower running at all on any speed. The defroster and a/c positions also yielded no results. Here is something that could be related to this problem. Last week my wife drove the car a short distance to town. She called when she got to town and said the power windows wouldn't work, the SRS light was on, the radio wouldn't work and I think thats all she said. Anyway, after she came home I went out and everything was fine. No lights on the dash, windows worked properly, etc. The only thing I noticed in the past about the heater blower was that it would squeak occasionally. I hope you guys have a few ideas for me to check. I'm going to read the faqs when I wake up :) Thanks in advance!
