My ac started blowing warm in the front, compressor was running and line was frosted over. I checked the rear ac in the 3rd row seating and it was blowing cold, but front is still warmer on both sides, manual controls
Return the right knob up to "Recirculate within cabin" mode. Still the same?
A 2002 Grand Cherokee (without rear a/c) flaked on me while driving 200 miles. I tried EVERYTHING to get it to blow cold, nothing worked. With fan on high, I rotated the knob to "defrost", and when I did that, several big chunks of foam blew out the windshield vent, and everything worked fine after that. I was 20 miles from my destination.
