a/c blows warm air when idles cold when running
it could be the heater core and ac housing unit that allows hot air to be mixed with the cold air or it could just cancel out the cold due to the motion of the car
Bad Thermostat
the aurora have two ac temp. sensor one of them are bad
Actually, the AC is always blowing cold air. Its just that sometimes your nerves can't feel it because your body is used to it.
The system is low on freon...........
You have a bad fan clutch..............
Try getting it recharged.
Well it should blow cold while driving and stopped. You probably need to get your AC recharged. Hope I helped!!
Sounds like it is low on freon. Probably has a leak.
heater hoses might have been disconected
You will need to replace the rear expansion block valve and the recharge the system with freon and oil..............
