Have you radiator clutch fan check out, sounds like its bad, air blows through radiator and a/c condenser while driving and no air blows through at stops, will cause a/c pressure to go up and not cool.

Electric fan for a/c has quit ,, the reason it is blowing cold while moving is because air is passing through the condensor... not so much when stopped.

    Radiator fans when checked are running but thbey dont seem to be fast as I have noticed in past summers, however car is running at normal temps, I just have noticed fans do not go all the way on (FAST LOUD) as I have heard in the past, might this be a problem? I have visually checked fuses look ok,when I engage the ac it goes on and goes off, but i dont notice that power drain it normally did when you engae it, and the radiator fans dont go faster like they used to? Any ideas??

    check the fan relays. Some of these control the fans fast and slow stages.

Also if the fans are working properly the condenser may become clogged with bugs and such wich will cause same effect as the fan issue as well especially if u have lots of bugs in your area seen that alot

I have same issue. I took to Chevy dealer they could not find problem (whats new) then I took to trusted mechanic.
They measured voltage at compressor and found out when idle the voltage dips below manufacturer specs, then when RPMS go up it gets more juice so the compressor then starts to work properly.
Chevy claims its made that way to extend compressor life.

Your equinox does not have a fan clutch. Fans are electric.

Possible that the idle speed is not up high enough when air is on. car should idle higher when air runs. solenoid usually controls this speed. it could be bad.

SOURCE: AC blows hot air when i stop at an intersection or slow down.

Try cleaning the condenser located in front of the radiator , with either a garden hose or compressed air. If this doesn't cure the problem then have your a/c system checked for leaks and recharged.

2004 camry ac light blinking and throws hot air. Suggestions?


My 2003 Toyota Camry AC often starts blowing hot air and the AC light starts blinking. I don't know why the following process works, but it does. Using the temp selector (left) reduce the temperature all the way down to Max Cold and then push the Auto button. It will start blowing out very cold air. After a little while push the temp selector to the desired temperature.

While running down the street the ac works great. When I stop for a stop light the ac quits working and blows warm air. When the light turns green and I start moving again the ac works great.


two things are possible here. is the a/c fan working or not. this would mean you are not getting the cooling while setting still but are while moving. also you could be low on freon charge and this will happen. if this helps please reply and good luck

sounds like there is not enough r134 coolant in the system and when your slowing down the compressor stops turning. Have someone add some coolant and you should be ok.

Jeep Wrangler 03 A/C stopped working abruptly


This may be the AC compressor cycling switch is defective. It is located in the larger of the 2 AC lines coming from the compressor, it has a wire connector to it with 2-3 wires. To verify this is the issue jumper the connector with a small piece of wire and see if the compressor runs.

Nissan 2000 ac hot when idle


the a/c condenser has a fan in front ( there is actually 2 fans if you sit on the car it will be fan on right side ) if this fan does not
come on immediately when you are parked and engine in idle
there is a problem with power to it, or motor failure. If you drive it
on the highway and a/c operates fine that's because air is circulating though condenser (thats what the fan is supposed to do at idle or slow traffic)
