2005 Moon Roof Leaks

Post by jmvvibeowner » Mon May 31, 2021 12:46 pm

Hi. I have two water leak issues from the moon roof. My car has over 200K miles. I have water leaking down my A-pillars from the moon roof. My moon roof leaks from the two rear corners where the gasket meets the metal roof. I checked the front drain tubes, flushed them and they drain fine, but water still leaks into the car down the A-pillars.
Does anyone know how to fix the moon roof leak and would anyone know why the water leaks into the car even though the front drains work fine? Also, are there rear drains? I could not see anything when the moon roof is open.

The seal isn't 110% waterproof. It is designed to let some water into the sunroof assembly.

It's possible the front and/or rear drains are still clogged.

It's also possible that the windshield seal at the roof is bad or you have rust under it. That could also cause water to run down the A-pillars.

Last I checked RockAuto had the sunroof seal listed under the matrix...it's the same sunroof for the Vibe.

Thanks for your response zbyers. Since I last posted about this I've noticed that I have water coming in the front center of the moonroof when it leaks, on the passenger side in the center of the moon roof and the entire length of the back of the moon roof. My front passenger seat and floor got very wet after a few heavy rainstorms we had.

Does anyone have any idea what it will take to fix this and what it might cost? My car is a 2005 with 226,000 miles on it and still runs great so I don't want to get rid of it, yet I also don't want to pay a fortune to fix this leak.

Would a regular mechanic be able to do this or would it need to be a body shop? Would they need to just replace the gasket around the moonroof?

Thanks in advance.

Vibe Owners 070721 Passenger Headliner Leak, no moon roof.

Dear Vibe Owners, I have a Headliner Leak on the passenger side of my 05 Vibe, from the joint where the headliner meets the plastic covering the roof column. I do not have a moon roof.

The problem was previously diagnosed as a leaking windshield. I was going to have my windshield replaced, but Safelight won't replace it because of some corrosion at the top of the windshield. I bought Fix Tape Rubberized Waterproof Tape, for Boat Repair (Clear, 4 inches x 5 feet), and put it all the way across the top of the windshield. The leak continued.

It appears the leak is from the luggage rack, and seems to be coming from the driver side luggage rack. When I covered the passenger side luggage rack and tested it in the rain, the leak persisted. So it has to be coming from the driver side luggage rack.

Has anyone else had the leak problem? How did you fix it?

coppens1, you need to find the exact spot where the water is coming into the cars interior. The only way that you will be able to do that is to pull the interior trim and head liner out. Use a forceful stream of water and start spraying down areas of the car and watching where the water comes in it.

Water will migrate to other areas as you drive down the road. The wind will take the water and push it around and up channels and seams. The main thing is to know where the water is coming in at, so the inside is the place you need to start. You have to see the crack, opening, seam, etc. that is letting the water in, then go to the outside and start investigating that area for damage.

If Safelight will not replace the glass because of corrosion, then you more issues. You may have to go to a body shop for the repair around the windshield. They will not know the extent of the damage until the windshield is out. If sheet metal is rusted away, the body shop may be able to repair the windshield opening and then get a good seal on the new glass.

Just because you taped the top of the windshield does not mean the leak is not there. As I stated above water does migrate and it could come up the sides of the windshield and under your tape to find the hole to the interior.
