Greetings everyone.  I got a call from my selling dealership that the fix is finally in for the rear window  defroster of my 2018 GMC Sierra Denali.  I’ve only had the truck since the end of July of this year.  So, I called to schedule an appointment today and the service writer tells me they need 3 hours for the fix, and that the entire rear window must come out.  Am I missing something here ?  I only thought it had something to do with the brass or copper contacts but thought it could be done without removing the window.  I’m just a little worried that they won’t put it back together properly and I’ll end up with window leaks .  Everything is great now except not having a rear defroster.  Has anyone had the fix done yet ?  Any issues ?  Any feedback is greatly appreciated.  Happy Thanksgiving to you all ?

Thank you sir for your reply.   I did have the two front door and rear door windows tinted, but I think the rear came tinted from the factory?  I’m hoping that they do a decent job and not butcher any

I have a 2018 and haven’t heard anything or received a notice. I pulled the fuse months ago. I paid out of pocket to have my rear window tinted. Guessing GM isn’t going to reimburse for replacement window to be tinted.

obviously the quality of the reinstall is going to depend on the tech(s). 

 

@STRMTRPR posted in this thread 

that he had the recall done already. He’s probably about the only one so far so he’s probably the guy to ask? 

 

Hopefully your dealers idea of the fix isn’t replacing yours with a solid window... I’m with you can’t imagine the fix requires removing the window? No wonder GM has been dragging their feet so long on this one....

I think they have to remove the window to access the heat element circuitry below the window. They wont be replacing the glass, so your tint should remain intact when you pick it up unless the recall states to removing window tint which is highly unlikely. Most rear windows are tinted except for the odd WT spec where some people prefer an clear window which is an absolute nightmare for night drivers.

Well this is the  fix GM has decided to do.

  • GM Recall #:
  • N192220470
  • Transport Canada Recall #:
  • 19988
  • Date Issued:
  • Jun 27, 2019

Recall Title:

Power Sliding Rear Window Defroster Failures (Canada Only)

Recall Description:

General Motors has approved a safety recall in Canada for certain 2014-2019 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a power sliding rear window (RPO A48). In some of these vehicles, areas of high electric resistance on the rear defroster circuit, caused, in part, by mechanical stress from opening and closing the rear power window, intrusion of debris, and use of the rear defroster may, over time, generate heat which could melt the areas surrounding the circuit. In rare instances, this heat could cause a non-propagating fire, increasing the risk of property damage or injury.

Safety Risk Description:

In some of these vehicles, areas of high electric resistance on the rear defroster circuit, caused, in part, by mechanical stress from opening and closing the rear power window, intrusion of debris, and use of the rear defroster may, over time, generate heat which could melt the areas surrounding the circuit.

Repair Description:

Dealers will replace the buss bar covers and the contact cover, and for certain vehicles, will reprogram the HVAC calibration to disable the rear defroster from automatically turning on at keyed start. Please note that the rear defroster will automatically turn on during remote start or by pushing the manual button and is not affected by this calibration. If the rear window or sliding glass assembly appears damaged due to an occurrence of high electrical resistance on the rear defroster circuit, they will also be replaced.

Nice, I got the brake recall so when I take it in for that I will schedule the rear window as well.

I have the sliding rear window with defrost, and according to my build sheet, I also have the heated outside mirrors although there are no symbols or wording on the outside mirror glass. I could really care less about having the rear window defrost because I have a topper on the bed anyway.  But I dont want to lose the function of the heated outside window. I am assuming if I pulled the fuse for rear window defrost, I am also going to lose the heated outside mirrors as well. Is that correct?

I've never used the rear defrost in any of my trucks so I just pulled the fuse.

I've read somewhere in this forum that some of the guys have deactivated their rear defrost and connected their AM/FM Antenna to the wire on the back window, after they have done the Antenna Delete.

My truck is built the same way, the mirror defrost/heaters are tied into the rear window.  Believe that there should be an image of your side mirror on the rear defrost button.  Straight out of the OM Page 50.....

I go Tuesday 

If possible could you please give us a brief description on what the dealer did and if the whole rear window has to come out?  I had a bad experience with my selling dealership, don’t really wanna go back there ....

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
