New to me, 2000 Cherokee XJ, has been having some sporadic AC issues.
When the truck is cold, the AC cycles ON/OFF every 4 seconds and does so for the first 10-15 minutes of running. Electric fan stays OFF.
After 10-15 minutes, clutch engages and the AC stays ON consistently. After some time (5-30mins), for no reason, it just stops. Blower continues but the clutch disengages and AC stays is no longer ON. Then it won't work for a while... Im not sure why it starts to again, but eventually it starts to work again. Sometimes not until the Jeep sits for a few hours, sometimes soon after its been parked... I have no clue where to start. Electric fan seems to come on later than i think it should, but it does eventually come on. Blower works 100% and there is plenty of hissing when i press the shredder valve on the low pressure side (near the canister at the passenger side fire wall).
Basically, works when cold then stops when the truck gets hot. Any ideas? Im stumped...
