My 2001 Pontiac Sunfire runs good. AC pressure is in green.

My AC blows hot air when idling but runs normal at highway speeds.

Could be freezing up due to air and moisture forming ice and blocking off the orifice tube, low pressure, clutch, vacuum and actuator, bad temperature sensor and HVAC condtrol moduele
