I have 2013 Yukon XL Denali with 32,000 miles on it and the A/C recirculate does not seem to work. It has been to two different dealers and they say the system is working as designed. The light comes on, but you still get all the outdoor pollution and exhaust from traffic into the vehicle. I...

We took our 2011 Acadia to the dealer today for an air conditioning problem. Although it is 6mo past warranty and 2000mi past factory warranty we have the $0 deductible major guard extended warranty. They charged the system, added dye and said no leaks were found. Being that they found no...

I have a 2002 GMC Yukon that has the air only blowing through defrost and floor vents. I recently had to get a new battery and this is when this started. I have already tried the recalibration trick where you unplug the battery or HVAC fuse for several minutes and then plug back in and put the...

Hi, my name is Scott and i just purchased a used 2005 GMC Sierra. just like all used vehicles it needs a few things repaired. I am currently working on my A/C and heater controls. The heater is stuck on, no matter what possition the temperature is set at. I know there are a number of things...

Hello, I have some issues that I think are electrical, just not sure. First thing is the A/C shuts of randomly, it shuts off and comes back on within 30 secs. The Max A/C only blows from the defrost vents. Second thing is the dome lights stay on all the time no matter if the door is open...

This is driving me nuts. My 2000 GMC Jimmy 4.3 2 door, James as we call him, has been sputtering for about 6 months now and I have run out of ideas as to why. Its not all of the time but at least 75%. I have replaced the distributor, rotor cap, spark plugs, serp belt, fuel pump, temp control...

I have a 2000 GMC Sonoma SLS Ext. cab. When I bought it about 6 months ago, the A/C only worked on the two highest settings; 3 & 4. Since I got it in the middle of a freezing cold winter, I wasn't too worried about using the A/C on any low settings. Recently, it stopped working on the highest...

hello all. I have been searching on here and only finding bits and pieces. I would like to know if a malfunction in the transmission can cause problems with the A/C system... Or vice versa. the back story. I saved a 96 jimmy from the wrecking yard june 2012 from a friend of an acquaintance...

The computerized climate control worked fine until suddenly it started cycling hot & cold & blowing high & low, no matter what the setting. There are even strange sounds of vents opening/closing when the system is off. The A/C appears OK, as the system is charged & the compressor engages when...

When the low side pressure starts to rise up and gets to about 45 , a burst of air/fluid comes out from the rear of the compressor ..it only happens at this higher pressure , not before . If i release enough pressure so that it does not climb up to this 45 and stays down at around 35 , will i be...

My Air Conditioning does not blow cold air. The heating and ventilation is all fine but when I turn it the knob to cold it continues to blow room temperature air out of the vents. Any advice?

I just purchased my 2003 Envoy a week ago. I have noticed that the A/C compressor activates when the re-circulate button is activated. The A/C switch is off,... The compressor only activates though when the blower fan is on. If I turn it off,... the A/C compressor never starts. I confirmed...
