Too much heat (archive)

Posted by Glen on November 25, 2001 at 21:57:00:

I've been working to get my heating and A/C right. ('94 740iL)

Here's the current state: I'm getting heat from the driver side (only) defroster when I shouldn't be. If I switch the A/C on, the "flap" closes and the flow of hot air stops. If I dial in a temperature that would call for heat, I correctly get heat from the other vents.

I've replaced (w/new) heater valves, resoldered the 120 ohm resistors in the control module, removed dust/lint from around the cabin temp sensor, installed a fresh microfilter, used contact cleaner on micro-switches in dash control unit.

I'm looking for advice on what to try next.
Thanks!
