Thanks for sharing, I hope you were successful in repairing your truck. WTF! I just learned my truck may have clogged drain tubes or a leak in the rear cab brake light. I only recently discovered last week that my floorboard behind the driver's seat is damp: I thought I either left my door ajar or the seals in the door frame or rear window was leaking. I was conversing with the guys at O'Reilly's and one guy inquired if I had a sunroof - yeah I do have a sunroof! It is making sense to me because I started having a sagging headliner 2 to 3 years ago. I thought it was Florida humidity, but Geez Louise, I pray that the inside of my cab roof isn't rusting. Last night I checked my sunroof and I noticed the plastic parts are cracked - I hope I can fix my water leak problem.
Today I searched for "2005 GMC Sierra 1500 sunroof leak" and this video shows up in search list. Too funny, I commented on this video four years ago! Guess What? It was a long four-(4) arduous years of identifying the three-(3) sources of leaks [cabin pressure vents, third brake light and the rear windshield and repairing them. I resolved the cabin pressure vents and 3rd brake light, but I found a great mechanic whom identified and repaired the rear windshield leak. Two weeks after getting my headliner replaced in June 2023, I get a brand new water leak! I brought it back to the Great Mechanic and we learned that the front passenger drain tube is cracked; consequently, water finds its way into the passenger cab during rainy days. I am back to covering the truck with a tarp. Once I retrieve my parents 1997 Monte Carlo LS from Time Saver, I will leave my truck for the Great Mechanic to repair. My brand new headliner and carpet on the front passenger side has gotten soaked twice, once when I didn't know the drain tube was cracked and the second time when I didn't know that there was a a lot of pinholes on the tarp.
@nineirondesign I am having this issue as well. Before I saw this video I sealed the spots where the tabs are located, as both sides were leaking. Bad stuff. I’m not sure what you mean when you say the water is wicking itself into the headliner. Can’t I just seal that space between the track and the channel?
I would really appreciate a response. I’m wondering how good of a fix would it be if I was to just seal the outside clips and not seal it from the top. Thank you
@@kerrycarpenter9422 yes from what I can tell so far. I smothered rtv sealant all over those clips to seal it really well. I flooded the roof for 30min with a garden hose and didn't see it leak at all. Haven't had any rain yet though.
I just separated and sealed it with a silicone for plastics and windows. Then shaped it a little to help the water channel where it should go. But sealing the connection should keep the water from wicking it's way in to the headliner.
@@nineirondesign Ok, I think I have the exact same issue..very irritating. Hard to understand how all of the sudden it randomly starts failing and wicking the water. Can you explain again how you created a better drip edge with silicone. I read your response above but still am having a hard time imagining what it looks like. You reshaped the plastic or the silicone you applied?

Wish my 2000 suburban had no sunroof
hmmm was there no way to clean the drains so it would function as designed ?
The peice that you called a guide would there be a part number for the part from gm?
Thanks man at least I know where to start now

Where can I get a repair kit for this year. Will an 07 kit work? That's all I can find.
Not sure, but did you attempt to blow out the drain lines with an air compressor? Those get clogged sometimes.
How has this been is it still holding up
Still no leaks a year later. Thanks for asking.
nineirondesign where does the water go once u seal it up?
I would really appreciate a response. I’m wondering how good of a fix would it be if I was to just seal the outside clips and not seal it from the top. Thank you
Not sure as I've only had experience with how I fixed it. And it's holding up to this day. And it's been a rainy year. tks
I had this same issue with mine. I dropped the headliner and rubbed RTV Sealant over the bottom side of the three little clips
Did the rtv work on the tabs my started yesterday?
@@kerrycarpenter9422 yes from what I can tell so far. I smothered rtv sealant all over those clips to seal it really well. I flooded the roof for 30min with a garden hose and didn't see it leak at all. Haven't had any rain yet though.
@@austinwilson930how is it today?
Thank you for this video. I am going to try this. What did you use for the drip edge?
I just separated and sealed it with a silicone for plastics and windows. Then shaped it a little to help the water channel where it should go. But sealing the connection should keep the water from wicking it's way in to the headliner.
Does the whole headliner need to be removed for fixing this leak ?
It'd at least have to be dropped down to the dash level with seats reclined.
