so it started back when i got my truck, it was under warranty still and they replaced all the seals. but not that we have been getting more rain lately, my sunroof has begun to leak again. the water will come out of the plastic that surrounds the sunroof on the inside, the one that is like 3in wide. it doesn't happen every time it rains, usually just when it has been sitting for a day or so. does anyone have any ideas on where this is coming from? it is the stock sunroof.

same exact thing happens to me and i really dont understand it.

My brother pontiac has a blow off drain and a bunch of shit came out and is no longer clogged...
However, on ours i cant find anything of that nature. Best i can gather is that somehow its getting past the seal when there is standing water since its actually lower than the roof itself, then dripping onto the inside and gathering up on the lip under the rubber. When you turn/stop it all rushes forward and spills out onto your seat, or your lap.

The manual says to wipe the seals with warm water once a year, but maybe there is a type of grease or something that would help create a better seal...

my brother call me today to tell me my sunroof leaked last night, so i told him to take it to the dealer (he works there). they looked at it and could not get it to leak, but he said the tech was going to clean the seal and put dielectric grease on the seals

#07-08-67-001B: Sunroof Leaks Water, Wind or Whistle Noise from Sunroof (Determine Source of Leak and Apply Sealer) - (Jun 22, 2009)


Subject: Sunroof Leaks Water, Wind or Whistle Noise from Sunroof (Determine Source of Leak and Apply Sealer)


Models: 2005-2009 Chevrolet Colorado

2005-2009 GMC Canyon

with RPO CF5 Sunroof




--------------------------------------------------------------------------------

This bulletin is being revised to add the 2009 model year. Please discard Corporate Bulletin 07-08-67-001A (Section 08 -- Body & Accessories).


--------------------------------------------------------------------------------

Condition
Some customers may comment on water entering into the vehicle from the sunroof area. Other customers may comment on a wind noise or whistle noise heard from the sunroof area when driving at different speeds.

Design
The sunroof module is designed to be completely sealed at the roof panel to help prevent water from traveling past the glass panel seal. The sunroof glass assembly does not have any glass panel adjustments. The sunroof assembly does not contain a water management drain tube system. When operating the sunroof, the glass panel moves rearward and slides up above the roof panel. Therefore, the vehicle must be driven or the exterior dried off sufficiently to remove excessive water prior to opening the sunroof glass. If the water is not sufficiently dissipated, some water may enter inside the vehicle.

Cause
Some earlier built vehicles with the sunroof option did not have any adhesive sealer installed on the upper sunroof frame assembly.

Wind or Whistle Noise Test Procedure
Determine the source of the wind or whistle noise. Refer to Air/Wind Noise in SI.

Water Hose Test Procedure
Perform a water hose test to determine where the leak is entering the sunroof assembly.

Important: Use a water hose without the nozzle attached at a controlled medium volume water flow.





Visually inspect the sunroof glass. The glass should be flush to the sunroof frame. If the glass (1) like in the graphic above is not flush, make sure no parts are broken or missing from the sunroof module assembly.
Make sure all seals and tracks are clean and free of debris. Use a dampened lint free cloth with warm water to clean the seals. Use GM™ Glass Cleaner, P/N 89021822 (in Canada, 992727) to clean the tracks.
Open the sunshade to the full open position.
Open the sunroof window to the full open position.
Remove the four outer trim cover screws located outside of the sunroof module.
Remove the outer trim cover.
Remove the sunroof front trim cover. Refer to Sunroof Front Trim Cover Replacement in SI.
Have an assistant inside the vehicle to signal you when the leak is detected.
Perform a water test to verify the leak concern.
If a leak is found, try to pinpoint the exact location that the water is entering. It could be any of the following four areas:
10.1. The leak may be entering from the roof panel and upper sunroof frame.

10.2. The leak may be entering from the upper sunroof frame seal and lower frame.

10.3. The leak may be entering from the sunroof glass and glass seal.

10.4. The water may be entering from around the sunroof glass clip holder.

Dry off the sunroof glass, outer sunroof frame and the roof panel.
Tape off around the entire outside perimeter of the upper sunroof frame assembly and outside the roof panel with masking tape.
Start water testing at the left front outer roof panel and sunroof frame by removing one inch of tape at a time until the source of the leak can be pinpointed.
Proceed with the water test while removing the masking tape along the right front outer sunroof frame and roof panel until the complete area has been tested.
Tape off the entire area around the outside perimeter of the sunroof glass and sunroof frame with masking tape.
Proceed to water test up to the sunroof glass and sunroof frame.
Start water testing while removing the masking tape from the left front corner of the sunroof glass; then proceed along to the right front corner of the glass until the complete area has been tested.
Have an assistant signal you when the leak is detected.
Note the area you are water testing and mark the entry point of the water.
The leak could be from more than one area, so determine which conditions apply and follow the recommended corrections below.
Condition 1
The leak condition is present between the roof panel (1) and the dry seal on the upper sunroof frame.

Cause 1
The dry foam seal on the upper sunroof frame assembly may have collapsed or has become distorted, causing the leak.

Correction 1
Remove the sunroof module assembly and apply CRL7711 Sealer (a one-part butyl adhesive) to the outer edge of the upper sunroof frame using the procedure listed below:

Remove the sunroof motor. Refer to Power Sunroof Motor Replacement in SI.
Important: Note the size, color and locations of the lower sunroof frame screws when removing them.

Remove the six (black) TORX® screws from each side of the lower sunroof frame.
Important: Do Not remove the (red) TORX® screws from the track.

Remove the eight (gold) TORX® screws from the lower sunroof frame.
Remove the lower frame from the sunroof module assembly.
Important: Have a clean workbench with a flat protective cover. The cover will help protect the sunroof glass when the glass is placed face down on the bench.

Remove the sunroof module and window from the vehicle and place the glass side down on a clean bench.
Tip
The sunroof window can now be manually moved forward or backward.

Manually close the sunroof window to the sunroof module assembly.
Clean the outside area of the upper sunroof frame with GM™ Glass Cleaner for vehicles built without adhesive under the sunroof frame. If the sunroof frame has adhesive applied to the frame, use masking tape to clean the frame and seal.



Clean the outside roof panel area (1) around the sunroof opening with GM™ Glass Cleaner if no adhesive has been used. If adhesive has been used, it may be necessary to use masking tape and a 3M™ General Purpose Adhesive Cleaner, P/N 08984, or equivalent, to clean the roof panel.
Apply GM Super Lube® with PTFE, P/N 12371287 (in Canada, 10953437) to the outside bare edges of the roof panel opening for the sunroof module. This grease is recommended for use on any bare edges around the sunroof opening. An acid brush can be used to apply the grease.



A caulk gun applicator will be needed to apply the adhesive (1).
Tip
You may want to use some disposable gloves to keep the adhesive from getting onto your hands.

Apply a 2 mm (1/16 in) bead (1) of CRL7711 Sealant around the entire edge of the upper frame assembly and dry seal.
Install the sunroof module assembly back into the vehicle.
Install the lower sunroof frame to the sunroof module.
Install the screws into the lower sunroof frame assembly.
Tighten the screws in the lower sunroof frame using the cross-tightening sequence.
Tighten
Tighten the screws to 3 N·m (27 lb in).

Manually push the sunroof window to the full open position. This will allow the window, motors and cables to be timed.
Install the sunroof motor. Refer to Power Sunroof Motor Replacement in SI.
Verify the proper operation of the sunroof.



Clean off any excessive adhesive (1) from the roof panel with a plastic-type scraper/razor blade while using a 3M™ General Purpose Cleaner, P/N 08984, or equivalent, as shown in the graphic above.
Perform a water test to verify the leak has been fixed.
Install the sunroof front trim cover. Refer to Sunroof Front Trim Cover Replacement in SI.
Important: A clicking sound can be heard when the retaining clips snap onto the upper frame. Open the sunroof and visually inspect from the roof area that the retaining clips on the front trim cover are installed properly.

Install the outer trim cover and four screws.
Tighten
Tighten the screws to 1 N·m (9 lb in).

Condition 2




A leak condition between the lower sunroof frame (2) and the upper sunroof frame (3) at the window weather seal (4).

Cause 2
The seal on the upper sunroof frame assembly may not have enough sealant under the seal.

Correction 2
Apply GM™ Weatherstrip Adhesive, P/N 12345097 (in Canada, 10953479) to the weatherstrip sealing flange located in the upper sunroof frame.

Condition 3
A leak from the sunroof window glass and sunroof window seal.

Cause 3
The sunroof window seal may be deformed or compressed, not allowing the sunroof window glass to seal properly.

Correction 3
Replace the sunroof window seal following the steps below:

Open the sunshade to the full open position.



Remove the old sunroof window seal (1) from the frame (2). Refer to Sunroof Window Seal Replacement in SI.
Install the new seal. Refer to Sunroof Window Seal Replacement in SI.
Condition 4




A leak from around the sunroof glass holder clip, known as a "blow out clip" (1).

Cause 4
A lack of adhesive sealant under the sunroof window holder clip.

Correction 4
Remove the sunroof window holder clip and apply a small amount of CRL7711 Sealant in the upper frame clip using the steps below.

Remove the power sunroof motor. Refer to Power Sunroof Motor Replacement in SI.
Remove the lower sunroof frame. Refer to Sunroof Frame Replacement-Lower in SI.
Remove the two screws from the sunroof gear plate.
Remove the gear plate.
Remove the gear.
Remove the two screws for the sunroof glass holder clip.

does anyone know the dimensions of the sunroof drain tubing? a part number will work too.

over the weekend i pulled down the headliner and removed the a-pillar trim to find the drain hose had been pinched, thus preventing flow. i free'd up the pinch the best i could and turned it over. i would like to replace the drain tubing but need to know the sizing.

thanks

What kind of truck do you have, too have found the drain tubing?? I have 06 GMC Canyon. I know I'm late with this, but I have been dealing with this leaking top for the longest.

hello. i own a 2011 GMC canyon crew cab 4x4.

go to amazon and search for interior trim removal tools. buy the set with about 12+ pieces in it, ~$20. use these tools to safely remove the plastic trim around the windshield and in the footwell. behind you will find the drain tubes. look for leaf matter, sludge, and crud. disconnect the crimp at the top and acknowldege its installation. remove the tube and use hot water and maybe some bleach to clean it out. replace it back into location and you're done.
