I have a 01 Buick and the ac temp that comes out of the vents is around 50 deg - at idle and around 45 deg at highway speed - Is this normal a normal temp? or should the ac temps be colder?
Yes, in fact in most modern cars the AC automatically comes on with the Defroster.
Ceiling. Cold air fails
The air on the outlet side of the air handler should be approximately 18 degrees colder than the air on the inlet side.
55 degrees to 60 degrees
15-20 degrees cooler than the air returning from the home to the air handler.
In some cars. one belt drives both the alternator and the air conditioning. In other cars, each has its own belt. Depends on the car. The alternator belt runs whenever the engine is running, the AC belt turns, but is only running under load when the AC compressor is turned on to get cold air.
Your AC system probably needs a recharge. AC units in cars need regular servicing too - about every couple years is adequate.
If it's cold outside do you want cold air blasting when you get in your car?
There should be at least a 12 degree split between the incomming air and the air comming out of the vents.
Simple, you ac does not blow cold air even though you have it turned on and the temperature set to cold.
why does ac blow warm air? why does ac blow warm air?
a/c blows warm air when idles cold when running
