My top is leaking a little in the back corners during very hard rain (or car wash). What should I be doing to fix the problem, weatherstrip or adjust etc?

 

You may be putting the top back on wrong. I have done it a few times.

There are water channels in the back corners of the car. Make sure you are not folding or pinching any of the car's weather stripping when you put the top back on.

When you do the water has no place to go but into the car and not down the drain channel.

Take the top off and look where the 2 top's pins go. You'll see a "flap" of weather stripping. make sure you are no blocking the drain hole when you put the top back on.

 

Here is the roof panel adjustment, just in case.

Roof Lift Off Panel Adjustment
1. Perform one or more of the following five adjustment procedures to properly align the roof lift off panel.


2. To adjust the front striker for up down roof alignment perform the following steps:

A. For major up down roof adjustment loosen the striker bolts and reposition the latch striker up or down.

Thanks for the info, I'll check it out to see if I installed it wrong.

 

Haha...yeah adjusting it doesn't sound fun...honestly on my 2000 coupe it had been parked outside by previous owner i'm sure and the seals were just shot...I got new top and top rear seals from GMpartshouse.com for very reasonable prices and replaced them all...looks great and no leaks whatsoever and...it really cut wind noise from the slightest of gaps I had. You do need to be carefull when putting the top on with new seals tho as mentioned...there is a correct way for them to puzzle piece fit. You will not find the seals in good used condition as i found out because you will destroy the old ones upon removing them from the car. When installing them take extra care on fitment...I wound up with one buckle in the top rear seal on the driverside. Doesn't afftect its performance just looks a bit uneven in one spot. Hope this helps.

Upon further inspecton, my Coupe rear seal is torn at both corners. Looks like it is time for a weather strip change. Anyone have a PN?

 

Mine are also torn, if you just don't let them flap over you'll be fine until you get some new ones.

Seriously...go to gmpartshouse.com
go to catalogs, chevy, collision
then select your model year, chevrolet/geo then corvette
When it goes to the parts list on the left go to roof, roof and components, upper w strip and it will show you the left and right top weather strips...then click the link saying show illistration and follow the # links to the full length back weatherstrip. These are the only 3 pieces you should have to replace inless you notice any further items you need. After looking around nobody has these items or kits aftermarket and most dealers and certainly body shops wanted to charge me full price but gmpartshouse is able to sell quite a bit lower than msrp...good luck and be careful and patient if you decide to replace them...PM me if you want advice on it.
