Automatic Air Conditioning Issues

I am wondering if anyone is experiencing temperature issues with the automatic air conditioning system in their Canyon or Colorado?

 

Bought the 2016 Canyon in April and currently have logged 6,500 miles. About 6 weeks after purchasing I noticed that the cabin temp would get warm after about 15 ~ 20 minutes of driving. We drove the truck from TN to SC on vacation at the end of June and the problem became very annoying. The cabin temp changes so much that we have to adjust the temp setting to LO and then it will respond after a few minutes. The fan changes speed but the air continues to be warm. On our return trip from vacation I noticed that once the air started getting warm if I stepped on the gas enough to engage passing gear the cool air would return without adjusting the temp. I have been able to repeat the step on the gas process to change the temp many times.

 

Today I have my truck at the dealer for the second time to check out the A/C issue and a 75mph+ vibration problem. The first trip I was told that the A/C systems was operating within MFG spec and I should use it in AUTO. I have been using AUTO and when that failed to keep the set temp I switched back and forth with the same results both ways... My confidence is not high that they can correct the issue.

 

I am new to the Forum and have been reading about the Vibration issues and thought I would ask about the A/C issues. This is my first GMC and at this moment it does not look to promising..

mine has 1600miles on it and it started having AC issues at about 1200 miles. At first I thought it was just with the auto mode on the AC but I have since been able to reproduce it with manual mode only. It will blow cold air and then it will blow warm air for a while heating up the cab. I need to contact my dealer and see what they can do about it. I got rid of a 13 yr old tacoma that had ice cold AC its whole life to this and I'm not happy.

Nothing new to report yet. I went for a ride with the Service Manager last Wednesday and was able to reproduce the issue in Auto/Auto mode. The truck initially cools and then starts blowing warm air. I can tell when is happening by the condensation that forms on the vents. The SM was not sure how to respond when I could change the temp by stepping on the gas...

 

I now have an appointment for next Monday for them to take another look at the issues. This will be trip #4. We will see.

I had the same thing happen, first they said it was normal. I had to call gm and log a complaint. They kept the truck a whole week and had it idling trying to replicate for gm techs. They finally asked me to come in and get it to blow hot. I replicated it within 8 minutes. They had the truck connected to the computer while I replicated the issue. They concluded it was the compressor and expansion valve. Replaced both and been working great since.

The thing is, they have to show the compressor fully open at 100% while the air is blowing warm.

I have a 2016 with 11,000 miles. I have found an intermittent problem in which the heat wont come on. Crank up the temp and the fan goes to full but its blowing cold air through the defrost. Even manual mode won't heat the air up. Of course when I go to the dealer it starts working. I want this fixed before winter, but it has to not heating before dealer can diagnose it. Frustrating but I still love this truck.

I just started having this issue.  There is nothing wrong with the compressor because when it is working, it blows colder than any other A/C system I've ever had.  It will literally freeze me out if I have it on Lo, and I live in Arizona.  The problem is either electrical or something with the computer / controller not sending a signal to activate the compressor.  I've checked fuses / relays but if it were either of those, it wouldn't be intermittent.  It would not work at all.  It's frustrating because I do all the maintenance / repairs on my vehicles and am very good at it, but this problem needs to be diagnosed with computer diagnostics equipment, and unless they can look at recent log files, the problem would have to be occurring while it was being diagnosed.  I don't want to take it to the dealer because I have 42K miles and it's out of warranty for this type of problem.  I was hoping to find the answer in this forum but it doesn't sound like anyone has a definitive solution.

I have a 2016 Colorado LT V6 and drove home from work A/C worked great. The next morning got in it to go to work and nothing. I checked fuse and relays they were all good and even changed the low pressure switch still nothing and it has a good charge in the system checked with gauges this one has me stumped for sure.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.
