Rear Window Defroster now being fixed under recall in US

TTT · March 6, 2020

I just brought my 15 Silverado last week in for the Brake recall issue and whilst i was there I was informed there is a recall on the rear defroster, their paperwork notes changed electrical contacts, not very descriptive I know, anyhow the next day I got a letter from GM regarding the issue was under recall. So for anyone interested in it this is some news for you. Not sure if its only trucks w/ the rear defrost and power slider or any truck with a rear defroster.

Do you have the recall number? Years affected per the letter?

I'm curious to see if it will be the same as the Canadian recall.

If so, that means another trip to the dealer this year..... Yey....

Wow, I was just posting my experience,

2017 GMC Sierra truck window shattering, software or hardware issue?

One crappy day, On March 5 2020 morning I remote started my truck and about 10 minutes of warm-up and 2 minutes of drive. Pulled in friends driveway and bang, back right rear sliding window shattered. Glass mostly spidered but blew out over Tonnele cover and ground. My first thought is holy shit, wtf. Not knowing what happened if somebody threw something at me or got hit with a pellet gun, had no idea. Wasn't happy. So I called my insurance company having glass coverage with 0 deductible and was set up with a appointment that afternoon. when I went back home I did some research online and found that Canadian built GM's had a recalls and some local US built vehicles had also complained about the rear sliding window with defrost. Again not knowing how this happened thinking this just could've been a random failure or accident. So I call my local GM representative and provide him with proper information and ask is there a recall on my specific vehicle. Yes for a block heater cord but nothing for rear window but stated I was not the first. I already know about cord, so I asked to file a report of my incident about the window and he said General motors will look at these reports and depending on how many they get will decide if this is a campaign or recall. I have a case number. Also told me since my vehicle was still under warranty to have it done at local dealer. Ok thank you, Contacted my local GMC dealer to get window replaced, I was asked my information, knowing I'm not in their system because I did not Purchase or have them service this vehicle. I got it 2 months ago. I was told they can look and evaluate it and then have to get approval from GM and then schedule an appointment. When? We can look at it this afternoon or tomorrow morning but the glass won't be replaced until mid next week OK looks like you're busy thank you very much. So having zero cost and getting it done today I went to my afternoon appointment, when the local glass company removed my rear window I was curious and asked to take photos of it I visually see the contacts from the rear sliding window to the window grid was discolored and the plastic was melted. Took many photos. In my personal opinion this connection overheated I believe shattered the glass? Took about two hours because you have to remove part of the backseat to get two connections for sliding window motor and defrost grid, replaced with OEM glass. Thank you, glass company for doing professional job especially on a black vehicle, job well done, happy guy. So I come back home call my local GM representative again to give them personal additional information for my report and stating I'm not happy this could've been a fire and destroyed this vehicle or injured someone sitting in that backseat when glass shattered. So is this just a random issue or should it in the future there be a campaign or recall.? So here's my unprofessional thoughts if this happened to you and you want disable rear defrost and still have the function of your remote control. This is only an issue when you remote start your vehicle and may prevent this issue to happen to your vehicle. I'd rather have my remote control features then rear defrost. By looking at some of the resources and schematics I think is when you remotely start your vehicle in short, the HVAC module looks at outside and inside temperature/humidity sensors and at start up choose climate control i.e. seats, F/R defrost,mirrors as a default to turn on at temperature XX degrees to Pre cool or heat. All these features are in remote start or climate control in settings there are options to turn on and off these features, I have set rear window defrost under climate control to off. Does not work. Tested and verified with temp meter, rear defrost indicator light does not Luminate when remote control start is used until key is in on position. Grid still gets hot. fix and possible prevention, since the rear window defrost and heated side view mirrors share the same switch and use the same circuit relay under the engine compartment and splits into a 15 amp for the heated mirrors and a 30 amp for rear defrost, remove 30amp only. Everything still operates as normal using the remote control, heated mirrors will go on and inside temperatures will be set, but will turn off when key to on position. When and if you need heated side view mirrors just press rear window defrost button, will illuminate and function heat mirrors only, no rear window defrost. Who needs rear defrost anyway but I can just put the fuse back in and take my chances of shatter window. So back to the beginning is a software fix or parts/hardware ( vehicles w/Heated Rear Sliding Window ) issue and may need to addressed or I just had one unlucky day. If you read this this far thanks for listening and this may prevent someone from injury or save you $600 to $800 for window replacement. easy prevention if it becomes an issue in the future

Senior dude, thank you for your interest in my post. Wouldn't have made any difference if I told you I'm handicap and I use a speech recognition software to write my words. What's next spellcheck.

Stick to the topic thanks my friend

Thanks for the novel. This is old news.

This has been a US recall since January.

You could have taken it to your dealer and had them replace it. They should have fixed it but said they weren't aware of a recall. B.S. go to another dealer.

Thanks, your right about dealer bs because I never used them before but two different gm reps just took my information and said nothing about recall. This was two days ago. Had insurance and truck will not fit in garage, that’s why I had glass company get it done the same day, like I stated I just got this truck in first week January and my window Shattered two days ago. This issue is the first I heard of it. Could anybody please forward information about Rear sliding heated window recall. Thanks in advance

I may have to replace it again if oem replaced window is on defective list. Great.

Well, you can moan about it, but presumably you want some help. A humongous block of text like what you wrote sucks to read, and lots of people will just skip it.

And yes, spelling, punctuation and grammar also make a difference. If someone reading your post has difficulty trying to figure out what you are trying to get across, again, most people will just skip it rather than spending a couple minutes trying to figure out what you wrote.

Of course, you can continue to post your 2000 word diatribes as a huge block of text, and perhaps someone will figure out what your problem is, but there aren't a lot of those people around. I'm simply trying to enable you to get the help that you need.

Dark side of the moon · March 8, 2020

Thank you very much sir and yes you're right I am looking for help.

I am new to this forum and I was just looking for some real informative answers, not necessarily criticized for my words but I do thank you for your help
