GOT THE FIX!
Problem is 100% GONE!
Just pulled the door panel on my company truck. I did take pics but, I'm not too good w/ posting them(I will try later but, don't count on them) sorry
The problem seems to be a lack of proper lubricant. Simple once the door panel is removed.
Basically, all you need is a can of white lithium grease spray, about an hour and some basic hand tools. After lubricating many,many garage doors, I will tell you that white lith grease is MUCH better and longer lasting than WD40(which can make the squeak worse believe it or not)
Behind the manual window crank is a nylon pully and a spool of braided cable. the cable winds around 4 other nylon pullys(one at each far corner of the door panel)
The squeak comes from the bottom 2 pullys. Once lubed, problem is GONE.
Absolutely nothing to do with window tint(mine dosen't have any) or weather stripping.
To remove the panel on mine, I removed the torx screw on the crank handle, removed the two exposed bottom screws, the two bolts behind the handle screw cover, the exposed screw right under the arm rest, the speaker cover and speaker, then lifted straight up. The panel has "hooked fingers" to latch the panel in place.Obviously, it will be a little harder with power windows.
Be very careful removing the door panel as I broke one of the plastic "fingers". Did not seem to affect anything that I can tell.
May want to be carful on spraying the grease as I went ape s@#% and sprayed everything so, I will probably have to keep cleaning the glass for the next week :o
This is DEFINITELY the problem and whatever tech said it was tint is lying through his teeth and just didn't want to fix it.
good luck, hope this helps.
I will respond in a week or so and let you all know if it's still good.
