Thread: Sunroof still leaks...FOUND PROBLEM FINALLY

Yup.

My yearly maintenance is to blow out my drain tubes with an air compressor. Some times I will even pour a little bleach down them and flush them out to keep things from growing in there and plugging them up.

I like the idea of covering the sunroof with plastic and taping the edges really well and soaking the whole top with water from a hose and sit and wait/watch.

That's how I found my trunk leak. I got in the trunk with a flash light, and had somebody outside with the garden hose.

~F~

These are very good ideas, that i didn't even think of. I found the leak is dripping off this silver round part of the sunroof motor, it seems almost that its leaking under the sunroof motor itself. The plastic idea seems like it would work well. Other wise I was thinking of possibly doing a whole entire headliner/sunroof tear-down when it gets a little warmer outside . As of now i have a t-shirt shoved into the opening for the interior light. If anyone else has any other ideas feel free to chime in.

Does anyone know the best way to get to the 4 drains? Do I have to remove the headliner to find them?

removing the headliner is the only way. You have to leave the headliner in the car, since its too big to fit through the doors

Ok, I think i fixed it! It was thunder storming, raining like crazy yesterday for a few hours and I put a paper towel where the water would run down. I checked it at the end of the day and the paper towel was still dry! My theory was my sunroof window was out of adjustment, leaving the window slightly opened, letting in too much water for the tubes to drain, Here's what i did to fix it...

-Locate the 6 torx bit screws that hold the sunroof window in place from inside the car, there will be 3 on each side, 3 above the passender seat, and 3 above the driver seat

-I loosened all of them, letting the window move around freely up and down.

-eyed it up to the outside so the entire window was almost flush with the roof, just so you can see the rubber seal sitting ever so slightly above the roof itself.

-tightened them all down good, then tried the switch to see if the window opened and closed properly, and it did, when the window closes properly it will sink in just a tad and seal up well.


so far no leaks yet

Im still keeping my fingers crossed

My sunroof still leaks!!!

Anyone with a 97-03 gp w/ sunroof step in!!

Im thinking of replacing the entire sunroof assembly...

I found the probem. FINALLY!

My sunroof rail is cracked. I found it yesterday, its in one of the corners and water is running down the valley of the sunroof, going through the open crack, running down the passenger pillar and down the opening for the sunroof switch and onto the floor and shifter. What a whore. Ill take pics, in case anyone else runs into the problem. Im ordering a newer entire sunroof from an 04 monte carlo through ed morad. I believe there are 2 different style sunroofs

97-99's are one design

00-03's are a different, better made design.

God. What a pain. 9 months with a leaky roof.

CG on finding the official fix.

LoL thanks man, I am kind of on my own with this one, no one else seems to have this exact problem. I guess because the majority of the community have 00's-up

Update: Today i picked up my new 04' monte carlo sunroof that i had ordered through moradpartscompany. They were extremely helpful and got me a mint condition sunroof. I put it in and all seems to be well. Ill update on the next rain storm.

Sunroof wind deflector ftw it works till you fix the problem of adjusting the sunroof. eBay sells them for like 50 bucks or so for a 10 minute fix.

that would be your on-star antenna leaking. That's a very common problem with the 04-up gp's. As i understand you just take off the antenna and glob some sealant under it. Should fix you right up.

and as far as my sunroof, yeah its finally fixed, its been a few months and im happy to say I fixed it

whats the diff between the two roofs?

Is the onstar anenna bolted in underneather the headliner? Does the liner need to be removed? I've got the same issue going on.
