Where is the rain coming in from to collect in passager rear seat well?

Thanks

My first guess would be the rear winshield seal along the top outside corner has pulled away from the body enough to let water in.
I'm going through similar issues with my front windshield, thus the interior upgrade while the windshield is out.

But the seat is not wet on top just on the bottom where its puddling, is it still the seal or coming in else where?

ooH, that might be a different story. I would suggest feeling up under the rear panel (behind the rear seats when folded up) to see if it is wet there as well. The water may be running down behind that rear panel and collecting in the seat bottom.
The rear deck/panel assembly can be removed with 4 screws, then a sharp upward tug (to unlatch the tab on the backside from the firewall clip).
I honestly suspect the rear window seal, or possibly the drainage tube from the sunroof has become clogged/disconnected. (These are supposed to exit through 2 small holes that are visible with the rear decklid open, but I do not know it the tubes are metal, plastic, etc under the headliner area).
Check inside the headliner as far as you can reach through the zipper in that direction for moisture (or signs of it) and also feel around where the headliner dies into the side panel along the back corner near the rear deck.
Trace the route of moisture to its highest point.

Sunroof drain plugged drops water in floor if you are a sunroof type, if you are a targa, it is likely bad rear seal or seal not aligned right.

I have a sunroof, what do I do to see if it is?

Thank you

Definately take the rear deck cover off. The whole rear of the car is covered with a spongy rubber covering. If that gets wet, the water can wick all over the place... where it comes out may not relate to where it comes in. Plus you don't want that dampness against the car... it will everntually rust the bulkhead and floors.

With the sunroof open, look on each side, you will see a small straw size opening, Take fishing line or weed wacker line and feed it through the opening until you get no resistance.

Have you check the radiator?

Barclay

I found it today, Dan you were right, it was the rear window seal, top right side. Now what should I do?

Thanks

Buy a replacement and have it swapped out. I just bought one on eBay for about $40. R&R cost depends on your local glass installer, b ut might be as much as $150.
Well worth the cost, regardless.

The rear window is the tough one, try to find an installer that does 911's. I called around to get an idea and some of the installers won't even do rear 911 glass. Deep scars from the past.

As a stop-gap, you might try to put some silicone sealant between the window and seal on the corners.... not a long term solution, but will stop it while you are looking for a glass guy.

This is one of the truly bad design elements of the otherwise clever 911.... because of the shallow slope of the rear window, water collects in that corner and stays there until it either evaporates or works its way under the seal.....

I've found my leak ...bottom corner of the rear window. I've tried the silicone and doubt it even slowed down the leak. Fortunately for me, the car is gutted so I don't drench interior pieces and I can see where it drips very clearly. Any other ideas? Is it possible to r&r the same glass with a new seal?
