I'd much rather do this myself than let the dealer, who's going to have a tech work on it that really doesn't give a ____!
Back in 2018, I put some sponge rubber foam for air conditioner insulation in between the bottom hard plastic Velcro and the metal retainer. It worked for the longest time, but the noise came back. It's not necessarily clicking now, but it is ticking. If I put pressure on one of the offending areas (above the passenger sun visor), the noise stops. It's definitely the headliner.
I have spent countless hours trying to fix rattles, squeaks, ticks, clicks and unknown noises on this truck. Geez, with a $70,000 window sticker, this is just wrong!
Do you happen to remember exactly what 3M foam tape you used? There still may be time for me to give this one more try before I have to drop the truck off next Monday night!
I would be most appreciative!
