The bigger question is how did it lose the Freon to begin with. You can get R-134a at most parts stores and the fitting on the refill cans will only fit on the low side but if you don't fix the leak it will just go low again. try auto Zone for a refill or booster can if you are looking for that.

I have a 2002 pt cruiser that is blowing the ac 10amp fuse repeatedly. I mean within minutes of changing it. Also the ac is only blowing hot air. Can someone please help.


An AC system blowing hot air is usually due to a low freon charge or a non operational AC compressor. If the fuse blows, disconnect the compressor electrical plug and turn on the AC. If the fuse doesn't blow, suspect a compressor problem. If the fuse continues to blow with the compressor disconnected, there is a direct short between the ON/OFF switch and the compressor which can take hours to diagnose

2009 chevy AVEO 5 ac blows hot air


The guage needs to read between 35/40 psi.. If its much higher you may be overfull, this causes it to not cool.. Fix by letting some freon out, then top it back to needed pressure.. If pressure is correct, it would be a clog in the system.. Usually an orafice tube or accumulator..good luck!

I HAVE A 1995 SATURN CAR 1.9L AND THE QUESTION IS. THE AC BLOWS BUT ITS LIKE THE HEATERS ON, AND THE COMPRESSER ENGAGES BUT DOESNT BLOW COLD AIR, I CAN SWITCH THE POSITION OF WHERE I WANT THE AIR TO COME...


Most likely the freon has leaked from the system. Replacing it is a fairly simple process, but finding and repairing the leak is expensive (labor wise). Plus, in the States, federal law prohibits non-licensed personnel from working with freon and it's descendants. Find a good AC service shop and get an estimate--you may not need that AC air as much as you thought! Good luck!

Ac not working, blows hot air only. Recharged


Check the evaporator coil by sniffing the vents,floor is best, with your tester.

Today the A/C stopped blowing cold air yesterday it was fine, Nothing but hot air was coming our of vents


Look for leaks around the A/C hoses and compressor. You may just be low on Freon. When the pressure in your lines (amount of gas in your ac lines) is low, the ac will just cutout hence blowing hot air. try adding some freon.

AC does not blow COLD air


not a home mechanic job thats for sure ,check youre pollen filter isnt choked up if thats ok then you need a specialist repairer because the venturi offrice is blocked which means that the high pressure gas isnt going through the small hole causing it to stay hot.must ge er indoors moaning
