Rear A/C Blowing Only Hot Air?

71232 Views 63 Replies 22 Participants Last post by  scottmaggie
I have a 2017 Premier II with rear a/c controls. Front a/c blowing good and cold, rear blowing only hot air, regardless of rear temp setting. Tried it with Sync on, and no change for rear a/c. Am I missing something, or is a visit to the dealer in my near future?

Norm-agreed the Flex is a dated body style, but being low to the ground with bigger door, it was easier for my beloved to get in and out of--major satisfaction factor. Anyway, I'll continue to update the saga of Envision as it develops.
Update-Talked to dealer service yesterday and they have no idea when they will get the part they "think" will fix the A/C. Part on backorder from GM.This car is getting to be real pain in the rear. Need to research the Texas Lemon Law. If the part ever comes in, there is no guarantee that will fix it. Still have a loaner car, but would strongly discourage anyone from buying an Envision at this time. More as it develops.
How do you like the Terrain? Sorry to hear about the delay in fixing your Envision.
I like the new styling of the Terrain loaner. It's a nice size, and the Terrain Denali would be even nicer. Our old 2010 Terrain never gave any trouble whatsoever. Would definitely buy another Terrain.
Update-called dealer this morning and was told part will be here Monday. Said car would be ready mid-week. So, we'll see. More as it happens (or doesn't).
**Update**!! Just got a call from the dealer. Dealer received and installed the part they ordered, but it still did not fix the problem. They are back on the phone with GM. Don't know what they are going to do. Does anyone have experience with a situation like this? I did research Texas Lemon Law and it doesn't appear easy to just get a new car, without a hearing, and a lot of red tape and time. At this point, I am just hoping GM will make this right. Any suggestions appreciated.
Just picked up the Envision a few minutes ago. Service mgr. said it turned out to be a faulty temp sensor that was intermittently sending wrong signal to the system. Worked correctly all the way back home, and responded to changes made in controls, fan speed, temp, etc. Fingers and toes crossed. It was in the shop so long, I almost forgot what it looked like, but it does have great styling, at least to my eye. Mgr. apologized profusely, and I told him I understood, he didn't engineer or assemble the vehicle. With all the changes to vehicles each year, new systems, new models, etc., problems are bound to pop up, and intermittent problems are the very worst. Just glad to have it back.

Unfortunately, I have yet another update. After the last repair, and inspecting the car at length, I discovered some cosmetic problems with the repairs. The bezel around the nav screen was askew, and there were pry marks on the dash upholstery, the chrome trim, and the plastic around the nav screen. I had previously mentioned a damaged spot on the driver side door panel after the first repair attempt, and I also brought that to the attention of the service person. They have ordered new parts to correct the damage. I realize this was probably a difficult, tedious job, but obviously not inspected properly before returning it to me. Just cementing my resolve that this is the first and last Buick for me.

I have a 2016 Buick Premium II and am experiencing the same rear AC issues. My car is currently at the dealership and they have ordered an HVAC case? I am hoping they fix it and it doesn't end up to be a continuing problem. DO you have any updates? Is your AC working now?
So far, I have had no more new or old problems with my A/C. Not sure what "HVAC case" is, but feel the dealer service will solve the problem, whatever it is. Hope you get it fixed soon, and let us know how things go.
good luck. hopefully they've all broken already and there isn't a huge backorder still. took 5 weeks for us to get ours back last summer.
I have this same issue and has been a huge headache. This is my first new car purchase and already regretting. They gave me a loaner (that was not clean) uhh ok whatever it was a 2018 terrain so ok. Got the car back after a week and then upon getting the car home the tech who fixed it must’ve been wearing dirt greasy pants as grease was all over the front seats and the passenger seat cover was extremely worn down from them working on the unit. They said they order a new seat cover and clean my other seat when the new seat cover came in. So I’ve sat on a stained seat for the last week. While still waiting for the seat cover to come in I then found out the power plug and rear USB connectors no longer worked (previously they did before rear ac repair) then I also noticed the rear ac doesn’t get as cold as the front AC. They said they would look at it when the passenger seat cover arrived. Here I am still waiting.....I’m the type of person who is forgiving when companies mess up and truly impacted by ones actions to make something right. This has been a bad experience and I don’t think I want to buy a GM again. The majority of cars I’ve owned have been GM. This will most likely be my last as the service has been lackluster.

About one year ago, I leased a 2017 Buick Envision AWD 4dr Premium II from a dealer in Chicago. The vehicle is under warranty. Beginning in mid-May, 2018, I started having issues with the A/C. Specifically, the rear A/C would only blow hot. It took about a week to diagnose the issue, another week for the part to come in, and about a week to install the part and make the repair (Air Distributor Case Replacement). All four doors and the front and rear panel had to be removed and reassembled. The technician broke a piece of trim putting everything back together, and so I had to wait an additional week for the trim to come in and be installed. In the meantime, I was put in three different loaners and was at the dealership several times just to switch out the cars.

My records show that I first brought the Envision in to the service center on May 31, 2018. On June 27, 2018, I was informed that the vehicle was repaired and could be picked up. On the short drive from the service center to my office, I immediately noticed that the steering wheel leather was damaged and, more importantly, the front passenger side A/C was only blowing hot. A porter was sent that afternoon to, again, switch out my car for a loaner and take the Envision back in for diagnostics.

This afternoon, my service advisor told me that a new steering wheel has been ordered but will not arrive until early next week. Moreover, they were unable to diagnose the A/C issue and are consulting GMC directly for guidance. However, GMC is unsure of what could be causing the problem and is having the service center run a gauntlet of tests. Because this is running up against the Holiday, I was advised that the issue may not be diagnosed until the week of July 10. Depending on the repair required and parts necessary, it could realistically be another 3-4 weeks before I get the vehicle back. That would be 60 days in total without my car.

Bri-
There seems to be a pattern here, and it isn't good. Poor A/C system design, questionable diagnostic procedures, sloppy GM service work, and limited parts availability. Did I miss anything?
That sums it up. I came here before I brought the car in and was not optimistic about my outcome after reading others’ experiences.
I am a GM service tech at a GM dealer doing a HVAC and I have had this vehicle for over a month waiting for parts it sucks for us as techs also just started to put it back together today

Update - After the Fourth of July Holiday, GM contacted the dealership to provide a solution to the front passenger a/c blowing hot. It was something having to do with the improper connection of a connector wire. The fix was not as labor intensive as the initial issue with the rear a/c and seems to have been caused when the techs were putting everything back together after the initial repair. The dealership ordered the new steering wheel, which took about 4 business days for delivery - and installed the new steering wheel. I received my car about a week after I noticed the issue with the front passenger a/c blowing hot. The service manager dropped the car off to me, and handed me a hefty "goodwill" reimbursement check, which I was not expecting. It covered at least two months of my lease payment. I've had the car for about a week now, and it seems to be fully repaired. I'm crossing my fingers that there will be no further issues.
Good for you, Bri. All I got was a half-hearted apology.
Did get a car wash (big whoop), and so far A/C works as expected. But I do have another gripe.
My car is Premium II AWD, and going around a corner while accelerating, there is at times a shuddering feeling, as if the front and back wheels are not working together as they should. This isn't a deal breaker, but for the money, it should work better. However, after researching this problem, it seems that it might be major surgery to fix this AWD problem, which is apparently not uncommon to many AWD cars, and I'm just not ready for another extended hassle with the dealer service dept. right now.
The loaner the dealer gave me was FWD, and it steered and performed much smoother than my AWD. I'll know better next time.
Did you ever address the "wobble" you have? Mine does it really bad and it seems to be getting worse (11K miles) I have an appointment for the failed rear air (sigh) and also this wobble, which I am sure they're going to be "There is nothing wrong with this" Well dammit, it's a 48K car, it should not wobble. another issue I'm having, it seems to suffer power loss sometimes. Last week I pulled onto a highway and mashed it to the floor to get out in traffic and the car actually started hesitating like it was starving. Only done that once but the other times, I swear it runs like the turbo isn't working.
jonjon-
No, I don't plan to address the wobble, since it hasn't seemed to get any worse, appears to be a complicated fix, and I don't want another hassle with local dealer service mechanics. Mine is a lease car, and even if it weren't, I would already be thinking trade-in, rather than more repair hassles. But that's just me.
