Why does my AC blow warm air at idle?
Your AC system is low on refrigerant. Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. If the system is low on refrigerant, it will show up as AC blows warm at idle and blows colder when the engine is running at higher RPMs.

Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. If the system is low on refrigerant, it will show up as AC blows warm at idle and blows colder when the engine is running at higher RPMs. Get your system refrigerant level checked.
What happens to the fans when the compressor is idling?
When idling the compressor is rotating slower and the expansion valve closes slightly to keep the pressure constant at the evaporator. If the expansion fails to close slightly when idling the pressure falls off at the evaporator and the AC stops cooling. The fans are working.
Is the a / C in my Windstar hot or cold?
I have a 2002 Ford Windstar and the A/C has started blowing hot when i idle but it blows cold when I am driving. I had the compressor replaced back in February and the pressure is normal so it doesn't look like it has a… I have a 2002 Ford Windstar and the A/C has started blowing hot when i idle but it blows cold when I am driving.

When does the AC work better at idle?
The high pressure readings are only occuring when the outside temp is 90 or higher. Now that the temperature is down in the mid 80’s the pressure as went back down a bit and the AC is working better at idle. I know the pressure changes with temperature change but I’ve never seen this drastic of a change. You ever get a solution?
What to do if your air conditioner is blowing hot air?
If you discover this to be the reason why your car air conditioner is blowing hot air add Red Angel A/C Stop Leak to your vehicle’s air conditioning system to seal any leaks no matter how small they are before you recharge the system.
