Suburban overheating and air conditioner blowing hot


If you have a viscous fan hub have it replaced as it is not working. The problem you have is that the engine is not driving the fan to draw air through the radiator when idling so the engine overheats . When moving the air flow from driving cools the radiator and so the temp goes back down. If you have electric fans have the codes read to find the fault or check why the electric fans are not working.

Air conditioner stopped blowing cool air. Added freon. Worked well for a few days. Now only blows cool air on passenger side.


Chances are you have a pretty fast freon leak, and the passenger side will be blowing warm within a few days. I have the same thing happen on a couple of my GM cars, except my leak is very slow; warm driver's side, cold passenger side.

You can try and top off the freon again, but I suspect you're going to have to take it to a shop to find the leak and get it fixed. Plan on spending some big dollars for the repair.

Good Luck.

My air conditioner compressor is cycling on and off. The car is a 2007 Pontiac G6. Only blowing warm air.


Usually if its "fast cycling" its low on freon which means you probably have a leak also. After adding the freon to the proper level the fast cycling should stop and you should have cold air in the low 50 degree range coming rom the vents. You can buy the cans of freon with the pressure gauges built into them so you can gauge how much to put in. It's based on outside air temperature. Follow the instructions carefully and you shouldn't have any issues.

Air Conditioner stops blowing cold air when vehicle is not moving


plus one on the cooling fan problem. if it was low on charge then as you slow down, condensor temps and line prressures would raise therefore it would cool at low speed and and not when moving since the incoming air would drop system temp,reducing line pressure and then cusing compressor to cycle. the auxillary cooling fans must be on whenever a/c is on, if not, thats your problem. get this taken care of because if you get stuck in traffic, your engine will overheat also if fans are not running

at idle most a/c get warmer as they are not under load to circulate the freon at a rapid pace
changing the dryer is wasting your money won't change anything sounds to me as if there might be a vapour lock in the system. run the car for a week with a/c on max to fully circulate freon to see if the problem goes away if not go back to the shot tell them to check system with gauges on the high and low side to make sure that it infact is properly charged with the right amount and temp.
42-54 degrees is good

Air conditioner blow warm air after freeon


you could have a leak in the ac system which would be why you had to add freon. take it to a repair shop and ask them to check fo rleaks because adding more freon wont fix your issue if there is a leak.
