I cannot find the source of the water leaking into the trunk on my '92 SSE.

It looks like the rear center may be where the water is tracking.
The spare tire well has a small puddle in it.
The net is wet more in the center than sides.

Tell me where it'* coming from and the best way to seal it.
Thanks.

Probably from the rear window seal. There was a TSB on that a few years ago, and you're not the first to see it. I THINK it leaks between the glass and seal, not between the seal and car. You could experiment with a tiny amount of clear silicone and run a bead.

:?
I called the local Pontiac dealer and asked about the TSB.
The Service Mgr. called back and said he couldn't find one.

If possible, could you send me the info you've got on the TSB?
Should you find it, I'll give a heads-up to the Mgr. again and see if I can get this fixed on the factory'* dime.
He mentioned the only way to find it is to do a 'water test'...

Meanwhile, I'll get ahold of the Salesman I bought the car from at the Cadillac dealership, or, his Boss, and see if we can work something out.
I bought the extended warranty ($$$$$$$), but, it doesn't cover this, of course.

If they aren't willing to do something about it, I'll drive up there with a 5-gal. bucket full of water and tell I'll make 'em a helluva deal for $4999.95 for this water bucket!!!
I'm hoping they'd rather fix it and have a happy customer.
WAY better PR, in my book.

A TSB differs from a recall. They won't pay. I'll try to dig it up for you. Might be a couple days. 4 days if you lived in Florida, like Jr, but 2 days for you

Cool.
I'll keep an eye out for it.

What I found today is pretty interesting. :?
While at the muffler shop, I and "the muffler guy" were looking over the car and I popped the trunklid to inspect the seal and water damage.
He stuck his hand up under the left side of the fender and felt water. Imagine that.
We determined that the missing lower left corner of the window seal on the outside was definetly contributing to the leak. At the top, the seal is lifting out of the channel and has about 5 or 6 waves in it.
NOW, the trunklid seal at the left corner is not like the right corner. It'* missing piece of the trim at the corner, leaving a nice open area for water to flow...
The two missing chunks of seal, plus the lifted area at the top, MUST be where the leak is originating from.

The car salesman, when asked about this problem the first time I looked at the car and before I discovered the puddle in the spare tirewell after we bought it...assured me, since he said he'd worked in the autoglass industry for a number of years and his dad had a similar car with a similar leak and foggy taillight lenses...that this wasn't the problem!!!

Of course, we bought the car "as is", with no repairs implied or promised, but, this gentleman was asked about the problem, and I believe misled me.
I'll mention now that we test drove the car, not knowing the brakelights weren't working---the hazard lights were out, too---and the horn!
They fixed all this because it'* a safety feature(*). Had to.
I contend that because the salesman denied the trunk/window seals were a problem, yet, the car exhibited quite a bit of INSIDE condensation on the FRONT WINDSHIELD as well, this, too, is a safety issue and should be taken care of by the dealer...
To keep good PR, I think it wouldn't cost the dealer too much to just replace these two seals and send me down the road with a dry car instead of a $5000+ water bucket.

Whaddaya think?

Nail 'em to the wall. Do it in person. The last thing they want is an irate customer in the store. Make sure you start the confrontation in front of other customers. Your chances of success are much greater.

Hey! I missed this Forum! It was my first home on finding out about my Bonneville.
Bonneville Attitude was nice enough to have me over for visits while this site was down and they are very gracious. I'll continue to visit there often, but, this is where I'll probably be most of the time.

GOOD NEWS!
The dealer replaced the rear window/upper trunk lid seal at no cost to me and I'm a happy customer. Just got it done today and we'll keep an eye on it. Excellent!
