Re: Patrick, I still need some pics from you
Thanks alot for the help, guys. Unplugging the aux pump and installing the on/off valve sounds like a very sensible fix that can also easily be undone in the event of a need for heat. If possible, I'd like to see the diagram as well.
Is it possible that a bad IHKA module could cause un-asked-for heat in addition to the A/C problem I'm experiencing? The other day on the way home from work I had cold A/C on the driver's side and full-on heat on the passenger's side, even though both dials were on max cold. Of course, the A/C lasted about 10 minutes and then the compressor disengaged. The passenger's side returned to normal when I restarted the car after dinner.
Could a bad IHKA control module be causing this?
