I have tried to search for help with this but have had no luck with the search function.
I have a 2001 XJ that when I bought it had a slow leak in the AC system. Well this spring it turned into a large leak located in the evap core.
I finally broke down and tore out the entire dash to get to the hvac components, WHAT A PITA.
Well now that I have it all back together with a new evap, dryer, soft and hard lines, o-rings, evac and charge.
When I crank up the jeep in the morning everything works as it should. The gauges show proper psi, the compressor cycles on and off, and the temp out of the vents is in the lower 40's. I can rev the motor and let the coolant temp come up to 195-210. All good and woking.
BUT... as soon as I back out of the driveway and head down the road the compressor stops working. I turn around and head back to the driveway and nothing I do will make the compressor kick back in. The only thing that works is to turn it off and let it sit for an hr or so.
I did notice that when I turn the blend knob to floor the air does not come out at the floor, but when I turn it to defrost or vent it works as it should.
Maybe their is something going on with the vac pressure that makes the system think the air has been turned off? Is that even a logical train of thought?
Has any one else on here had this sort of issue?
