When I come to a complete stop my AC gets warm and the temperature goes up but when I back on the road everything is back to normal, when in park or natural I accurate and it cools down again? I replaced the cooling clutch assembly and the same problem, there is plenty of air flow over the condenser and radiator. are there any vacuum lines that control the hot and cold air flow doors? if so were are they. also I looked at some YouTube videos and some said that the plum door actuators could be the problem. are the voltage sensitive? because when I push the gas pedal it cools down again and the actuators are controls by climate control switches.

Good morning.

The first thing I would do is to have the Freon pressures checked.

Can you give me the high and low side pressures when idling? the pressures are critical.

I see you covered the other bases with air flow as well.
