Another Leaking Sunroof is now DRY!!! THANKS

What a blessing this web site is. I had tried everything and was getting ready to schedule a several hundred dollar appointment with the dealer as my '03 TB now sits outside all the time.

A $6 tube of silicone sealant and a couple of hours of seal and test, seal and test and the driver's side no longer leaks and the passenger side will hopefully never leak.

It sat out in 4 inches of rain over 4 hours yesterday and the headliner is as dry as the day it rolled off assembly line.

Thanks to all who make this web site possible.

Thank you!

I now have a better idea of what I'm going to find when I look up on my Denali...Every time this has happened, my truck has been parked in a driveway with a slant and it's been raining. Then when I back out and get flat, I've had the water drain through the sun visor holes all over me. Last week, it drained through the ceiling vent all over the driver-side middle seat...at least 2 cups worth...all over...

My next question is: I've noticed a great deal of discoloration of the carpet on the passenger side front and middle sections of the car. In the middle section, it's near the column/brace between front and rear doors. (Forgive me if I don't know the proper name of the parts...I'm a woman trying to diagnose these problems since nobody else around me seems to know much...). I don't ever carry liquids back there, what could it be and where could it be coming from?

I'll have to take a picture...someone's bound to know the answer for this GMC mess. (2003 GMC Yukon Denali). Thanks so much.

Replaced broken sunroof parts

Just replaced all the broken parts on the sunroof after the screw fell out of the rain trough and broke all the plastic crap and caused a leak. Put it all back in and now leaking like a sieve, will have to try pulling it all down and silicone everything, Nice work on the diagnosing.

GM has to be kidding me

This leaking nonsense is the next debacle with my Envoy Denali I'll be facing, and will be the last straw for me with this POS I own with only 42k miles on it.

Bottom line..will never buy or recommend another GM product to anyone..EVER. Word of mouth is the best advertising and I have absolutely nothing good to say about this POS I unfortunately made the mistake of purchasing...complete JUNK. Just jumped thru my butt to get the freakin' TCCM connections restored and the 4WD working again. Just waiting for next system to take a dump. Won't be long I'm sure.

My beater 1993 Jeep Grand Cherokee and 2001 beater Suby Outback blow the doors off this Envoy Denali in terms of reliability and performance. The ultimate effin joke when they advertise quality and perfection of these sh_t boxes. What a pathetic, poor excuse for a vehicle. Shame on them.
