My A/C Will not blow cold air. It is fully charged, with the correct amount of refrigerant. The compressor is kicking on and off, but even while it's on there's no cold air. Please help it's 101 in arkansas today!

 

is it blowing air or not at all, check ur expantion valve or orfice tube, not sure what style u have. it may be stuck up witha peace of dirt. also make sure u have 12 volts goin to every thing that will stop it too. hope im of any help i am just learning how to do a/c, but i only know how to do it on semi truck.

 

I'm having basically the same problem with my '95 Blazer. The mechanic is telling me he thinks it's an electrical problem. I get intermittant cold air...it last for about 5-10 minutes, the no cold air at all. I'll let you know what they find.

 

i just took my 2000 blazer in for work and i told them the compressor was leaking so they replaced a a/c thermal switch? I think thats what it was called, not sure y they changed it when i told what was leakin but they did. but if there is such a thing as a thermol switch then that may be the problem as well.

 

Wow! Thanks for the insight. Can you give me an idea of what I might expect for repair costs for that item?
