Just an FYI for everyone to get their trucks to the dealer to get this done, I don't know about my friends south of the border but it's fully winter here and I miss my rear defrost. Also note that the recall # and repair may differ for anyone in the States as this applies Canadian trucks only.

 

Mods, feel free to Sticky this if you feel it warrants that.

 

 

 

GM Program #:

 

N192270330

 

Date Issued:

 

Nov 08, 2019

 

Program Title:

Rear Window Defroster Thermal Events

 

Program Description:

Certain 2014-2019 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a power sliding rear window (RPO A48) had safety recall #N192220470 performed. This field action restores the rear window defrost function.

 

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. Dealers will also install the rear defroster fuse that was previously removed in field action # N192220470.

Have you had the work done?  Mine melted the plastic cover on the fingers that contact the outside window frame to give power to the center glass defrost circuit.  I tried soldering it back on and I don't know what solder they used but nothing I tried would stick.  It actually blew one set of the fingers off and took the plastic cover with it when it failed lol.  The fingers are all blued so they were not making good contact.  Truthfully I like to drive with the rear glass just cracked open  so that probably contributed to it although I never turn the defroster on... truck does that on it's own and I can't disable it for remote starts.  You can see the cover I mean in the bottom right hand corner of the middle glass.  

 

I'm curious what their repairs look like lol.  I'm fine with mine never working again as I do not use my rear window to look out of but if it's not a total butcher job I may go get the recall completed.

No I have not had the work done yet. Do you have pictures of your rear window? I'd love to see the carnage lol

I can grab one tonight haha.  I glued the melted back cover back on to hide the exposed contacts as this happened before the recall existed.  I will probably pop it back off again.

Finally. I've been waiting for this. Never had it disabled since I may have opened the rear window once. I'll take a defrosting window over a sliding window any day.

The piece that melted the cover and shot across the cab with the cover.  Yes I glued the cover back on and pulled the 30 amp defrost fuse.

Holy! I can't believe they actually had the potential of exploding.

Anyone have this work done, I just got the recall done and the work order says 1 22917202 25300 fuse, 1 84819605 164640 window, 1 84819606 164640 window.  Performed recall, replaced rear bus bar covers, terminal covers and fues. Verified heat damage not present.  HVAC programming not applicable.

 

The issue is that it rained like crazy last night and this morning my entire headliner along the back window from side to side was completely soaked.

How long did this service take?

Has anyone had the rear glass shatter after having the recall completed? I have a 2017 2500 that had the recall completed in July 2020 and the rear glass just shattered. The dealer says it's not covered under the recall.

      I love my truck but

      By taze · Posted

      Not exactly what I was hoping for, but I do like it. I wonder if they'll bring back Smokey Quartz Metallic? 🤔 https://gmauthority.com/blog/2026/06/here-is-the-all-new-2027-gmc-sierra-1500/

      Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

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

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.
