A/C Cutting out?

Anyone else seem to notice this? You're driving and the air feels great then for about 30 sec or so it feels as if the compressor cut off and it's not blowing as cold of air... then it eventually comes back.

Is this normal or should I mention this to the service dept?

Do you have the automatic climate control, if so it could be cycling on and off in an attempt to keep the temp constant, that's what it does...

No it's the full manual one.

If you feel only 30 seconds, it's gotta be the blend door.

I can shut off Air Conditioning and it is blowing cold are still left in the system for far longer than 30 seconds before I feel it blowing warm air.


Plus I say that considering how many people have come to the conclusion that the heat/cold is far from stable being discharged at the vents.

The blend door is software controlled (maybe even still on the not auto system?) which would require a software flash to make an attempt at a remedy.

@James Bell It's the normal "cycling" of the compressor. Even with the manual, the A/C maintains a cabin temp. based on your setting of the control. The compressor is also disengaged under certain load conditions to improve fuel economy. If it ran constantly, it would freeze the system.

I think the OP may be referring to something I have noticed in both auto mode and manual mode. The air doesn't just go from cold to slightly less cold like the compressor cycling. It goes from cold to warm like it's being blended with hot engine air. If the OP is referring to the air being slightly less cold then I stand corrected.

As the temps warm up here in AZ (already had our first 100+ F degree day) I'm obviously using my AC more. I will be taking my truck in and asking that they apply the "hose clamp" fix to the blend door whether or not it is cracked and that they re-learn the blend door. I'm going to bring the truck in next month when I need an oil change to have them look at this.

I have the same problem with my 2016 Colorado. It blows cold and then blows warm air (intermittently) even when my thermostat is set at 70 degrees. I have noticed this whether in "Auto", manual with fan adjustments, and maximum recirculation. This system is software controlled and will require a re-flash. It is noteworthy, that my 2015 Genesis and previous VW GLI both have/had the same type of software-controlled systems and I have never experienced this problem before. It appears to be a known issue and when my first oil change occurs (<49% oil life presently), I will direct the dealer to re-flash my system.


Too dang hot in Florida to put up with this!

I do notice that the worst issues seem to be when I am setting my HVAC at a temp close to the outside temp - if Outside temp is 72 deg and I set the HVAC to 71 degrees, it may seem hot, drop to 70 deg and much cooler.

I would definitely mention it and ask for them to do a temperature check with a thermometer. With the compressor cycling on and off the temperature of the air being discharged from the vents will vary by a few degrees but not enough to notice by feel. If you are noticing a wide fluctuation, something isn't correct.

I can tell when the compressor cycles off by the difference in temperature and moisture content of the air blowing in. In humid Fl. it's easy. The temperature of the air rises slightly but, since outside air is being drawn in and the refrigerant is not circulating, the AC does not remove as much moisture. I do not, however, have a problem with the overall temperature of the cabin.

As long as we are guessing here, Does it fail more frequently as the outside temperature rises?

If so you could be slightly over charged. There is a high pressure limit If I remember correctly is it 417 PSI. If you are overcharged you will trigger it more often when the incoming air rises.

I fought this on my Colorado when I first got it. It took me a while with some help from this forum to figure it out. I had to drive it with the gauges attached on a very hot day to see the problem on the gauges. Slightly reducing the amount of R-134 took care of the problem. I had recharged it twice by weight using an AC machine and it did not take care of my problem.

Good morning Riptide8,
I apologize for the A/C concerns you are experiencing in your Colorado. Have you been able to bring this to the attention of your dealership since it has started? Private message me with more details and I would be more than happy to assist you in connecting with a dealership to get this diagnosed.
Best,
Julianne M.

Just as a data point, I am also having the same issue. 2016 Colorado with ~1500 miles.

Mine has 5,000 miles on it. I took it to the dealership and he said he has another one there doing the same thing. And they are investigating with their research department or engineering department and they'll call me back when they have an idea whats causing it.

It's weird it'll freeze you out of the car some times (while making that funky AC smell) then within minute or two it's blowing like neutral temp air... not hot but not cold..... then eventually it comes back on but just cool.... not Ice Cold anymore. (This all happens to me during the day in the heat... and at night when there's not much heat)

My dad has a 14' Equinox that NEVER does this. And his blows that ICE COLD temp ALL THE TIME..... It's certainly an issue with the Colorado AC system or compressor (this was like this during 12pm in florida) constant ice cold air

My AC is blowing warm air. Compressor is running, blower is blowing. But it isn't cold. Dealer is picking up truck today and dropping off a loaner. Feel bad for the guy that gets to make the 45 mile return trip to the dealer this afternoon, it's going to be in the high 90's,both temp and humidity........

This exact situation happened to my wife and I just now on a 3 hr drive from the Phoenix area to the mountains. Really weird...we'll definitely be discussing this with our dealer next week.

So I'll add that mine is doing the same thing. 2016 Colorado 400 miles with automatic climate. On my drive to work early in the morning with just the fan on low (no a/c) and temp set at 70, but not in auto, the vent temperature would get warm then cold. It kept doing this no matter where I moved the temperature control. Eventually I shut the fan off and set the temp on Lo and it seemed ok.

On the way home, it was hot so I was using the A/C. At first I just left the temp control around 65, not in auto, and the fan speed about mid way. Again, the temperature would fluctuate really cold and then warm (not hot) air. I then tried putting it in auto with a set temperature around 68. It would hold fine for 5-10 minutes and then the fan would kick up to Hi and the air was no longer cold. Moving the temp control to Lo did not change it at all. If I tuned the fan off and back on it would work for a few minutes and then stop again. Eventually I turned the A/C off for a minute, turned it back on and left the temp on Lo and used the fan speed only to control the inside temperature and it seemed to hold until I got home.

It really feels like a control issue and not the a/c kicking out. I'm gonna play around with it some more to try and replicate the issue because if I take it in and it works nothing will happen.

I took my truck in for the my regular oil change yesterday. I also had them inspect the hitch for the recall (mine was the heavy duty hitch), update to android auto and I showed my service advisor the bulletin for the cracked blend door fix. I told him I'd rather have the hose clamp put on regardless to prevent a future issue. He agreed. Turns out the door was cracked so they put the clamp on and did something with the software (not an update). This did not fix the problem.

So, when I got home I let the AC run in the driveway and it turns out it does coincide with the compressor cycling. The compressor cycles off for what is in my opinion far too long allowing things to heat up far too much. Even if set the system to recirculate it still gets too warm. This is all software controlled from what I can tell and hopefully if GM gets enough complaints they'll change the cycle off time.

Got my truckette back yesterday. Some loose, random interior dash fastener was in the A/C and had jammed the mix door. The hose clamp fizx was already on my truck, apparently they are doing them from the factory mow. (Mine was built in June)
