I'd also recommend cerakote wipes to bring back life too all the plastic parts without painting them, they look more new and original. I did this to my escalade 04.
Bro I had that same problem with Tahoe. The rear hatch window wouldn’t open I had blamed it on my girl, not knowing it was my system that had mess it up lol. I noticed my bass was messing everything up my tv on the headliner would latch on to close and the tvs on the head rest were popping out as well. So I just took them off.
This gives me more motivation to finish my 2004 yukonxl 1500 build so far I got a pretty basic set up got 1 12 inch sub kicker competition with high quality Kenwood concert door speakers and I installed a Kenwood single din but here’s a catch I relocated the single din down to install a 10.2 inch 9th gen iPad as my head unit I installed everything my self the proper way and has pretty good loud bass and clear voice as well but I want more bass so imma add 4 15’s later on
And they are so easy to work on. Anything that failed on it, I fixed with the help of RU-vid of course. I had my 05 Yukon Denali XL since 2015 and I’ll never get rid of it.
