I just bought a 01 dodge stratus with the 2.4 DOHC. Initially I thought the AC needed a charge, but I put a pressure gauge on it and its holding at 70 lbs on the low side so I figured it was a relay. I replaced the relay, and I started the car. The heater control was on defroster, so I switched it to max AC, and got really cold air.
Here is the weird part. the AC clutch will only engage when you are on defroster, then go to AC, If I were to have the fan off, then start it on AC, it doesn’t get cold. but if I switch to defroster, then back to AC, it will be cold as long as the system is on. Anyone have any ideas how to make it come on from the AC setting on the controller?
I have already replaced the heater control on the dash, the AC relay, and the controlling fuses. Thank you in advance.
