Tailgate window is loose

I posted the following information under "Tailgate window/glass loose" in the Yukon and other large trucks forum. I thought this was a more frequent problem but I've only received one response, for which I think it may not be very common.

 

The window on the tailgate of my 2003 Yukon has popped up completely from one of the hinges that attach the window to the tailgage. Additional information on this subject is shown below (a copy from my earlier post). I need to go to my dealer but because of a bad experience with one of the dealers that I went to, I want to be prepared with as much information as possible regarding what I believe is a defect on the window. Please advise if you have seen or heard about this problem and what I can do to make sure it is resolved by the dealer.

 

Thanks.

 

Copy from my earlier post is as follows:

 

Has anyone had problems with their rear window/glass being loose on one or both of the hinges that hold it to the tailgate? This is for a year 2000 or earlier model.

 

I had a 2000 Yukon and approximately 2 1/2 years after I bought, it I had problems with both of the hinges that hold the glass to the tailgate becoming loose. One dealer told me I had broken it and another dealer accepted the fact that this was a defect and replaced the glass.

 

Now I have a 2003 Yukon and again, at approximately the same timeframe after I bought it, one of the hinges that holds the glass to the tailgate is completely loose.

 

I have less than 25k miles on it and park under a roof about 80% of the time. I don't think the sun is an issue. Both vehicles have been meticulously maintained. I also don't slam the doors or tailgate so it is definitely not because of abuse.

 

I have searched for service bulletins, recalls, etc. but have not found anything that relates to this particular subject. I am also preparing to go to the dealer and need as much information as possible. Any help will certainly be appreciated.

Yes, we see this failure. I wouldn't call it common, but we do maybe one a month, perhaps a bit less than that. There are no TSBs that I'm aware of.

Thanks for the response. I have one more question. I have a GM rear wind deflector. Do you recommend I remove it before taking the truck to the dealer? I want to avoid any problems replacing this part and don't want this accessory to be used as an excuse to the problem.

 

This has happened with and without the deflector.

Yep, this happens without anything extra added to the hatch/glass. If you can take it off without leaving holes or other obvious signs that something was mounted, it's probably a good idea to remove before going in.

I took the truck to the dealer and they immediately recognized the problem, what a relief. So the window was replaced and I'm back to being a happy customer.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉
