    My 2006 Lt did this, too. The dealership finally found out that GM puts two relay switches in the AC unit. You have to have both replaced. It will work for about a year, then guess it again. Part is only about $8.00 but the headache is months...

Actually there is a evaporator tempature sensor that has gone bad that is causing it to freeze up like that because it cycles the compressor on and off to prevent this freezup and vwhen the sensor goes badf the compressor will continuasly run all the time. $4e0.00 part.

The A/C on a 1999 Silverado 1500 blew cold one minute and the next minute it stopped blowing cold, what caused this?

Low Freon level can cause this. Do not try to refill yourself with a can. You will do more damage to it, because you have not evacuated used Freon and keep topping off externally will overload the system and spring a leak or burn the compressor out. Take it to a Shop where they will Evacuate, create Vaccum, inject Compressor oil and Dye and recharge to the require level with Freon. This way if Freon leaks you can see where the dye is coming out and fix the leak.

Ac blows cold air..then will blow vent temp air for 5-10 min...then back to cold air...about every 5-6 days or so. Had ac check...1# coolant added??no leaks per black light??? Air is cold when works.

The system needs to be evacuated with a vacuum pump before it is recharged. Otherwise moisture may be in the system which will displace and contaminate the refrigerant. Get it evacuated, the orfice filter replaced then recharge. Should be fine..

check the air vent of passenger side for any obstruction and secondly keep your thermostat full towards cold side make sure the ventilator is fully closed position and rotate the air selection knob clockwise and anti clock wise two three times than set it at the required position mainly your air selector seems to be malfunctioning there is nothing wrong with the ac

My 1995 Chevy Silverado blows cool air then warm air. It goes back and forth between cool and warm.

You have a flow restriction,the orifice tube,(inline filter) on the low side(suction)a/c hose.Check close by the dryer and lines for freezing over,if so evacuate,then flush a/c system,install new orifice tube and recharge with new oil and freon.

I have 05 chevy equinox. Air conditioner works and blows cool when traveling down highway. In town it blows warmer air. Had freon checked. They emptied it out, refilled it, and checked for leaks. All was...

No you have to change for a exchange unit ,best unit to buy is a bosch replacement a touch dearer but they are the best and last a long time ,with a diode out running to earth the battery will discharge overnight .now for the AC well the problem here is the coolong fan -- should run as soon as AC is turned which is why its cold when moving as the air flow is passing through but when stopped the heat isnt being dissapated by the front rad so the AC builds up pressure and the safety switch is turning it off .

Ac only cools when accelerator is pressed. when sitting in idle traffic, only blows warm air. had ac recharged, doesn't help.

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.

How do you replace a blend door on a 2006 Chevy Equinox? Is there a diagram? Car is blowing cold air...fluid level is good, pipes to/from firewall are warm.

Pull the instrument panel (dash board), remove the HVAC case, disassemble the HVAC case and replace broken door (G.M. Part #19130554) and reassemble. The job takes an experienced mechanic about 8.5 hours with air tools and electric screw guns, and costs about $1050.00 (including evacuating and recharging the A/C system.

Air conditioner not blowing cold after recharge last year

david_simko: based on your description above, it definitely sounds like you have a leak somewhere in your A/C system. If you re-charged your A/C system last year, you should still have plenty of freon (R134-a) coolant in your A/C system. If you are familiar with how the A/C system works on your vehicle, there are two products you can use to help you identify leak in your A/C system. The first is a liquid that you inject into the system. This liquid will come out (in a solid color) in the area(s) of where the leak is accruing. The second device is a electronic freon sniffer. This is a small hand held device with about a 10" antenna on it. This device electronically "sniffs" for freon, and leads you to the area of where freon is leaking. Since you've stated that you re-charged your A/C system last year, and since has degraded from cold air, to warm and now hot air, you will have to (at minimum) partially recharge your A/C system to use one of the two leak detection methods I have mentioned above. PLEASE VOTE FOR THIS REPLY IF YOU HAVE FOUND THIS INFORMATION HELPFUL. Thank you.
