Hello,
I have a 98 Dakota with a V6 and the air quits when it gets warm. I checked the pressure with one of those charger canisters with the gauge on it, it was a little low, but not much, it is fully charged now. The compressor cycles on and off and blows cold air until the truck gets warm then the clutch does not engage again unless the truck is shut off and allowed to cool. I temporarily bypassed the pressure cycle switch so the compressor runs constantly but the clutch still disengages, blows warm air and will not engage when the truck gets warm, (about 5-8 minutes). The radiator is full and both radiators are clean. Any help is appreciated.
Thanks,
George
