Small rain leak pass window I have a small leak on the passenger door weather strip on 99 Camaro Z28. What do I do to stop it before it gets worse? It is the door weather strip Not the T Top. Looked into replacing it but it comes in one piece that goes up around the T Top and was advised not to do it as it may start leaking around the T Top. Anybody have any suggestions?
Leaks in this area usually mean something in the door is broken. I would start by taking off the door panel and then checking for these two common conditions. Please report back and folks can advise on next steps:

It is not anything in the door. It is coming in at the top of the passenger window where the weather strip is. About a 4 inch spot where window top seals to weather strip. Window closes tight as it should. No adjustments to window needed. Had 2 leak tests and saw small leak at top of window. Determined weather seal has shrunk and wore down in that area. What can I use to prevent further leaking? Clear Gorilla Tape? Something similar that will not do damage?
It's a frameless window. If it was tight, it wouldn't be leaking.
Your previous post said that it was not the "top" of the window where the T-Top is. I assume you are talking about the angled front edge of the window along the A-Pillar?
If you can see through the gap, you most likely have a door geometry issue with the glass mechanism in the door. If the space is paper-thin, then it could be to the embrittlement of the weatherstripping. (You should still check for the regulator issue, above. If you ever had the window regulator removed and replaced with bolts (instead of the proper rivets), that will eat into the door skin and will start causing problems like the one you are describing.
If you have a properly installed regulator, then you can simply adjust the glass to seal more tightly against your weatherstripping. Just follow the shbox window adjustment instructions, exactly. (If you don't follow them in his exact order and with precision, the glass will get out of whack and further out of sorts.)

No. No one has written them up here or topped shbox's excellent write-up for the 3rd gen. If you go to the shbox site, his tutorial there is excellent and fills a gap for one of the few things missing in the Factory Service Manuals.

Had the window adjusted and that took care of the leak coming in thru the window. However I also seem to have a problem with water pooling on the back passenger floor when it rains hard. I pulled the plug under the car to drain but does anyone know where the drains are getting clogged so that I can clean them out?

You're likely dealing with a body seam or weatherstripping issue in the hatch channel.

I don't see any water coming in thru the hatch. I have water pooling on the floor back passenger side. No drips thru the window. Dry under front and back seat. No water in the cargo area.No seats are wet so not coming from TTops. Just the floor and around where the seat belt bolts to the floor. Where could it be coming from?

You may need to get new weatherstripping if messing around with your T-tops to get a better adjustment and flush fitting doesn't solve your problem. Also, you don't need to resort to clear gorilla tape. Man, I am self conscious as is about my gorilla tape work to get my aftermarket LS1 Trans AM style hood to work with my LS1 Camaro air box on my LT1 Trans AM. Hopefully this summer I can find a shop to fiberglass in a permanent rain baffle and make the hood legit. Trust me, you don't want to drive around with any kind of duct tape to solve a car's problem, believe me! This weatherstripping issue is something stupid, either the T-tops are not flushed up or crushing a drainage duct, or you need to replace the weatherstripping like I did.

Why would you think I need to replace the weather strip? I do not see and dripping anywhere down the interior walls. I originally thought to replace the weather-stripping and spoke with the owner of Interior Guys here and he advised me that if it was not leaking from my TTOP do Not replace it because it would surely leak from there if I did. I would not do that myself anyway. I do not have the skills to attempt that even if it was the problem. There is no indication that it is at this point.
