Moonroof not closing completely

[j91z28d1]

A length of string trimmer line works well to clean out the two drain lines.

I didn't think of that. I might just do that

ya that lube is not cheap, not the good stuff anyway, I bought some last year this was like $50
the small 15ml bottle is $25 this 2oz bottle is like 4 of those

gm parts sells some for the corvette targa tops too. it was dumb expensive for like 2oz bottle. but it worked and those cars are plagued with noisy and popping tops when you drive.

Thank you all for the great advice. I also wish there wasn't a moonroof in this yukon. I never had water pouring over my head in any of my other cars that didn't have one lol

I’ve gone deep into the metal sunroof to glass moonroof Resto on another vehicle. It’s a can of fried worms. I’m not familiar with GM’s sunroof mech but can tell you the best thing to lube a sunroof with is dielectric grease.

I never look out of my roof. I store cards and toothpicks there.

I'm not sure if you can find it anymore, but the oem stuff is pretty good for me. you put it on, let it soak in and then wipe off the excess. since I've been using it my 08 weather stripping feels better than some new gm's I've looked at. but I also have nothing to compare it too. I bought the car, the top drove me crazy and before I sold it, I tried this stuff and it worked.

other brands are probably good too

I use dielectric grease, Sil-Glide, or aerosol silicone sprayed on a rag, for weatherstripping.

It is amazing how much water collects on the roof after a rain storm. One morning I pulled out of my driveway after a rain storm, and I opened my sun roof, since it was a nice sunny day. After leaving my driveway, the road slopes down and eventually comes to a stop sign. I slowed down for the stop sign, and a RIVER of water came streaming down on me and completely soaked me.
