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 ?
