I have the same problem. The can of freon I bought said the gage should read 45-55 psi with compressor running and ambient temp of 80 degrees. In any case 25 psi is too low for AC to function.

My A/C blows hot air when stopped at a stop sign, idling, or sitting parked. Otherwise it seems to cool just fine. What could be the cause? Thanks.


check that the charge of r134a is sufficient in the system. When idling, the pressure should be 25psi to 45psi on the low side as measured by a pressure gauge usually on a hose connected to the low side with a can of freon.

I just put in freon and now it wont give out cool air


Is the compressor engaging and did it engage before adding freon?
What is the pressure on the gauge for the low side? 25psi to 45 psi is normal when the engine is running and the compressor is turning.

If the compressor is not turning the pressure should read 75psi to 100psi, before the compressor starts turning.

Also, the radiator fan should go on when you engage the air conditioning by turning it up to max.

If it blows, but not cold, Either you have a leak in the system, the condenser fan isn't running (although it would cool on the highway forcing air through the condenser.. It needs a partial charge with UV dye so any leaks can be traced...

Front air blows hot air while back air is cold. Can turn it off and on and it will work for a while.


I have the same problem, when running the air conditioning the front vents will blow hot air. I have not removed the dashboard yet, but I think that the air damper is stuck in the open position. It seemed like a heater core valve problem, but I am pretty sure it is a damper under the dashboard. Now however, I am finally getting some cool air out of the airconditioning vents, but when winter comes, I am afraid I will struggle getting heat again.

Air conditioner


If it's not taking any more R143a. You may have over charged it and the pressure switch is doing it's job by not activating the compressor. Over charged system will damage the compressor causing 100% failure. The low side should have 30psi to 50psi and the high side should have 150psi to 200psi to have it run properly. Any other readings will give poor a/c performance and a high reading condition will case system damage. If the reading are good and is at the manufacture's specification, the Thermal Expansion Valve (H block valve for Chryster)may have gone bad. These valve are prone to malfunction due to stuck, clogged valve with debris and corrosion. good luck and keep me posted, be glad to help.
