Since your a/c unit works well on the highway, this means it still has cooling capacity, although reduced.

This can be attributed to a low refrigerant (R134 or R12) which has a difficult time to cool and pressurize your cooling coil because of the lower RPM in stop and go traffic.

Have that checked out and see how it goes.

Hope this helps.

AC works for about 300 miles then stops and blows hot air. New AC compressor and freon charge. After sitting for a while it will again blow cold.


I think you have a similar problem to mine. At highway speeds is when it happens. And it is not blazing hot? Right?
Your evaporator is freezing up - as this happens the ice surrounding it prevents the flow of air over the evaporator coils and the result is warm air coming out of the registers. If I turn off the AC for about ten minutes and let unit melt the cold air comes back. This does not occur in stop and go driving.
I combat it by either running the fan at a higher than normal setting to increase air flow over the evaporator and then turning off when it gets too cold, OR using the air control to allow warmer outside air to enter into unit at highway speeds to prevent freezing up.
Newer cars have more sophisticated sensors and controls to prevent this but some older vehicles are subject to this anomaly.
Since it works fine under normal conditions I have not messed around with the freon level in system. If you release a tad of refrigerant the low pressure switch will shut off the compressor sooner and help minimize ice buildup. Good luck.

My air conditioning button stay lite all the time and the air doesnt work when the car is at and idle


if it stops working at idle or stop lights, the problem most likely is that the condenser is not getting cooling air from the ac fan in front of it
this results in a high head pressure and so the high pressure switch stops the ac compressor
take it to an accredited ac specialist shop for a proper diagnosis

03 Merc. Sable. AC works fine until I slow down in traffic, then it will slowly switch to blowing warm air


Have your a/c condensor fan checked out. It most likely is not working, or is not functioning at full speed. When you are driving air is being pushed through the condensor helping to keep your a/c cold, but when sitting in traffic there is no air flow if the condensor fan is not functioning at full speed.

Air conditioner not blowing cold air intermittently


you need a ac charge or the heater control valve is bad also check the compressor

stop and go traffic will make the car heat up,, make sure you have air flow through the radiator fins, also make sure that the ac fan is actually engaging the fans work on a sensor and if they don't work, neither does the fan.

check to see if your cooling fans are working because when they dont work, your air will blow nice and cold when driving but will be hot air when stopped in traffic.

Ac is blowing warm air in my 2005 sierra 2500hd duramax. Any idea


Your system has R-134 Freon in it. the 134 is made up of smaller molecules than the old R-12. The R -134 permeates through the rubber parts of the system. If the system gets too low on Freon, the compressor will stop coming on.(low pressure cut out switch). Have the system serviced with an A.C. machine that can vacuum, measure the amount of Freon in the system, and add the right amount. The machine can also inject die. Later the die will show up under a black light.This will show any leaks you may have.

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)
