The air conditioner tends to stop blowing cold air at idle for more than a few seconds (like at a stop light) and after about 10 minutes of idling the temp gauge goes through the roof. I don't remember hearing the electric cooling fans come on at any time.
How do I fix it
air conditioner stops blowing cold air at idle. Extended idling the temp gauge goes high and warning triggers. electric cooling fan is operating. At idle the compressor seems to be kicking in and out, pulling the motor down momentarily.
While vehicle is idling or in park the AC will turn hot, the RPM's begin to waiver and then the temp goes through the roof.
A/C running causes temp to start to rise if stopped for longer than traffic light, and cold air becomes warm. Also causes dramatic change in rpms when stopped.

Engine overheats when in idle or stop and go traffic and when the a/c is on. Doesn't happen all the time but it happens alot.
I have this same problem. The car can run alllll day long without overheating as long as I have the ac off. But the minute I turn it on and I'm sitting at a red light or just in park, give it a few minutes and it will start to rise! If anyone can give me any tips what can be the problem pleases email me at jayweaver1988@gmail.com
