Guys, I searched quite a bit and couldn't find anything...

I have a 2001 vert that is leaking water between the top of the driver side window and the convertible top. I want to replace the weatherstripping in this area but I can't find installation instructions/videos anywhere. Is there anything out there that you guys can point me to that shows/explains how the weatherstripping is removed and re-attached to the top? It's probably easy, but I like to research what I'm getting into before I start.

 

No one...?

 

I have the same leak, same side, same area so doing a 'search' for help. Maybe someone can lean us a hand??

 

I never did get a response on this and haven't had much luck finding anything. For now, I just don't drive in the rain and wipe it out after I wash it. Needs to be fixed though... I'm refocusing on my suspension upgrade for now, but plan to revisit this in late summer/early fall.

 

I have a1998 convertible with a passenger side leak. I found that new weatherstripping, either from GM or aftermarket is priced unbelievably expensive. Try to adjust the tip-in of your window and see if that helps.I did the adjustment and it stopped all but torrential downpours from leaking.The FSM has instructions on how to do it. Cultrag Performance, a forum vendor has GM weatherstripping but it is very expensive.

 

Yeah, that's why I've been procrastinating a bit on this. I need the 2 short sections which are $100 each! Hard to justify for a couple small pieces of rubber.

Well, my 2001 convertible has had a leak on the driver side since I bought it 7 years ago. The car lives in the garage much of the time, but if I got caught in a rainstorm it would drip on my left leg just above my knee. Very annoying, and plain un-cool. I tried all kinds of adjusting and fiddling with the window. Putting shims between the frame and the molding.
Good grief!!
One day I got around to taking a real close look at what might be different about the driver side vs. the passenger side. It seems that there was just a little gap at the top of the A-pillar and the convertible top on THE DRIVER SIDE, but not on the passenger side. After a lot of puzzlement, I eventually decided to try a piece of foam insulation in there. I have all kinds of junk in the garage, and I located a remnant of M-D Premium Sponge Rubber Weatherstrip.


This stuff is labelled for Door & Window - perfect!! (After all it needs to stop the window leak of my driver side door.) The dimensions of the entire weatherstrip is 3/8" x 1-1/4" x 10ft. This might be enough to do 200 Corvettes, because I only needed about 2 inches.

So I ran a trial with this stuff and was very surprised to see how well it worked. I unlatched the convertible top where it attaches to the top of the windshield. Next I folded the top back enough so it would stand open.



I cut a sort of triangle-ish shaped piece and put it in the recessed area of the molding that receives on the front end of the molding that fits into the recessed area of the molding that is attached to the A pillar the when the top is folded down.



DON'T glue/adhere your foam in this part. Instead attach it to the piece of molding that is at the front edge of the convertible top.

I folded down the top and re-fastened the latches. That piece of foam seems to be smashed in so tight that rain can't get in there.




I can report that after a few torrential rains - the frog-strangler variety - the water is being kept out. It is working so well that I am just going to leave it alone for a while longer. At some point I will possibly trim the sponge rubber a little and then infuse it with some 3M 5200 urethane sealant (I have a tube of it in black and it is very handy for certain specialized situations.) This same 3M 5200 is what I used to attached the triangle foam to the molding. It is messier than roofing tar at 100*. So wear gloves,mask the car and top excessively, and use plastic wrap (over the foam) if you fold the top back down before the stuff dries. Drying time can be up to 7 days according to the label/instructions.



If this helps you, or gives you any good ideas, please post up accordingly.
Good Luck.......

Thanks for the information. Mine drips a little bit on both sides near the rear of each window. I have tried to figure out why, but nothing looks bad. I thought maybe the weatherstripping is somewhat compressed and not able to keep all the water out. It's not bad, just a little annoying after washing it or getting caught out in the rain. It's not bad enough to make me want spend $200 for $10 worth of rubber.

 

Any chance you can share a few photos of your "fix" for us and send via email? I have the same exact issue, this sounds like it would work for us too.

Thanks,

 

How about if I post the pictures in the forum so others can also benefit?

 

Even better!

 

Here is a suggestion: Get some caulk backer rod (Lowe's, Home Depot, etc.); not sure which diameter, but I would start with the thinner stuff.....?
See if you can stuff enough of the backeer rod into that hollow channel that goes through the molding to "poof" out the width of the molding. I think that caulk backer is compressible to the point that you could push two of the smaller diameter pieces through together. And I think you could use a string to pull from one end also. Just attach the string first and use a real thing wire/stick to get the string out the other end first.

Hope that helps, or gives someone else an idea.

 

okay. Revised my earlier post and added picture, etc.

 

Thank you for adding the pictures. I bought the convertible roof weatherstripping kit and the leak and noise is still there at the windshield pillar (original weatherstripping) and the roof new weatherstripping. Where they meet has a small gap that gets noticeable at 45 mph and loud above 75 mph. Rain definitely gets through threre onto my knee.

 

I still have the car these many years later. I have water intrusion again from the same area and did another fiddly patch thingy to mitigate the issue.
Some problems are too difficult to solve completely. Perfect is the enemy of good enough.

 

Ok, I think I found the problem. I replaced the windsheild pillar weatherstripping and the convertible roof and rear roof pad weatherstripping. I had to use that Home Depot weatherstrip behind the driver's side upper middle and glue the GM weatherstripping to it. I also had to pop out that offending corner where the windshield pillar meets the convertible roof and glue those in position as well.

The window is still getting sucked out a 70+ mph causing a gap. The window is wobbling out/in more than the passenger side. I tightened the two bolts holding the window. The wobble is less. I'm going to get the door's outer and inner window rain guards as well. Hopefully that will solve this noisy problem. In the meantime, I have noise cancelling airpods.

 

Could you post a couple or 3 photos of the areas where you did this work?
It is amazing what I learn from things other members have to say and what I can see in the pictures.
Thanks!!

 

The is new Corvette Central weatherstripping. I also used the 3M weatherstrip glue. The window rain guards are on the way from Zip Corvette. The problem area is where the roof meets the windshield pillar.

 

LAGary
Thanks for that.
I agree. In my experience that is the problematic tricky area to solve.
Can you share the part number of the window rain guards from Zip Corvette? I went to their website and can't find those.
In the past I replaced the door window outer seals; I am not clear if that is the part on which you are waiting.

 

I just got them in today and installed them--they slide backwards then pop out. Do NOT try to pop out without sliding backward like I stupidly did--the fiberglass is fragile and I broke 3 of the keyholes or maybe they were like that already from the door repair at a shop I had done years ago.

This tightened up the window against the weatherstripping. I have not driven it but they passed the wobble test. My only trepidation is that the motor struggles to raise the window against the new rain seal.

Zip-Corvette.com part number: 98-04 Conv Door Window Outer Seals SKU# WS-4638

SUMMARY: The wobble is the source of my window noise/rain leak problem. I replaced the roof weatherstrip around the entire roof including under the rear windshield (ensure proper alignment to window may need home depot weatherstrip under and 3M weatherstrip glue to seal); replaced the windshield weatherstrip (yes, don't be lazy or cheap); tighten the two window securing bolts (the rubber seals have aged thinner); and replaced the window outer seals (slide them back, then pop out--do not just pop out).
