That I'm not sure.. You'd think the blower would still work on it's own in economy mode even if said sensor wouldn't allow the ac to engage because of a defect of some kind..

I agree that should in theory just disengage the compressor... it was only a thought. Do you think a wiring diagram would help? I can try and get one if you don't have one for that car.

I have one although it's rather hard to follow. There is Def a relay that clicks somewhere over on the right side of the dash when the fan comes back on and AC kicks in again. I need to run it till it quits again and see if I still have power at the fuse. Maybe that relay is getting weak..

If it's similar to the aftermarket kit my brother had on his 740 there was a relay behind the glove box somewhere maybe mounted to the blower housing or the ducting. Let us know what you find. Sorry I couldn't be more helpful
