On My 535i i have heat all the time ...ac compressor works and all but all there is is heat=HOT is it the heat valve or is my ac\heat control messed up
thanksk,nick
It's probably the heater valves on the left side of the firewall. I had the same problem, and loosened mine with a few taps with a hammer followed by exercising the solenoids with a 12 volt supply until they both clunked equally and solidly. No problems since.
