Q: Q: Truck slowly overheats only when AC is on and not moving

asked by on

Truck slowly starts to overhear when it is stationary for a few minutes and with the AC on. Does not overheat at all with AC on and truck moving. Does not overheat at all with AC off and truck standing still.

Water pump and thermostat are good. How do I fix this please?

Thank you
