Hi,
My 1999 Jeep Grand Cherokee Limited (98,000 miles) has an air conditioning problem. The a/c and heater have a mind of their own…sometimes they work sometimes they don’t. I checked the driver bender door shaft pin stop and found the pin stop is intact. I could manually rotate shaft 90 degrees and doors sound like they are opening and closing properly.
1st check- fault codes 7-1-2013

I unhooked my battery and calibrated AZC - HVAC system, then checked for fault codes. I have a 50 = Mode door travel range too large code. What is a mode door? After running the car again for a week I checked the fault codes again.
2nd check- fault codes 7-10-2013

On the a/c dual temperature control display, the left temperature readout is brightly lit while sometimes the right temperature readout is dimly lit.
Help?
1999 Jeep GC A/C and Heater problem
Re: 1999 Jeep GC A/C and Heater problem
to clear the codes (which are history codes): after you read the codes on the vehicles display you press a/c or recirculate for 3 seconds while the display is in fault mode. this will only clear historical codes. Current codes cannot be cleared electronically. They have to be fixed.

mode door it the door that selects what mode to operate in. defrost, dash vents, floor or combinations
