Air Conditioner Issue Please Help
hello, I have an ac issue with my car. last year it started, during hot weather the ac would stop blowing cold at idle. turned out was low on coolant. that solved the problem.
now, the ac wont blow cold at all, coolant measures approx 45psi and compressor does operate. I checked the air mix servo today and it works perfect. I checked the glass eye on the ac system under hood and looks fairly normal.
heater still works great. just dont know what else to check. please help.

Check to see if your cooling fans are funcioning properly. NOT the fan in the dash, the fan motors in the front.
Your condensor is not working properly, the compressor is not working, or your exansion valve is clogged, or possibly the blower/vents are the issue.
Your pressures should be much higher on the low and high side, espcially if the compressor is on.

When this occurs, does the A/C light flash?
