Aiea,Hi.
Ok anyone would have any idea why both rear footwells is drenched with water? No where else is wet just under the seat area. Could it be a leaking door seal,floor board plugs or quarter window seal? Any suggestions before I start ordering parts. Mahalo

If the rear footwells are filled with water, I would suspect the door seals are shot. But like you said, it very well could be the Quarter window seals or possibly the hatch seal if you have a hatch.
Before you start ordering parts, you need to see where the water is coming from. Your best bet is to get inside the car while someone sprays water from a hose onto the car in these areas and see if you can see it leaking in. You might have to pull the inner body panels for a closer look.
 
ive found if one set of seals are going out you might as well replace all the rest since they are not far behind. and CJPP sells the doors and hatch seals for like 45 bucks or something like that
 
I was thinking of just pulling the carpet entirely out and spray water in certain areas to see where it would possibly be coming from. I don't want to end up replacing parts I don't need because I plan on trading this car in the next couple of weeks.
 
Most of the time if the quater windows leak it heads right for the spot you are talking about. The rear hatch would get the trunk area really wet and the tops of the seats. The quater windows will allow water to run behind the interior trim right down to the floor and under the rear seat.
 
What body style is it? That way we can eliminate the hatch seal or not and help you better. I personally had wet carpet in the rear footwells also. I traced it up the corner (behind the bottom seatbelt attach point) and then felt that the seat was a bit damp/cold. From there I could see that water had at one time puddled in the little pockets nest to the rear seat bottom. I've a notch, so I started checking at the quarter windows & re-sealed them.

So would it be a good idea to just reseal the quarter window instead from the inside with silicone? instead of ripping the whole thing out and replacing the exterior seal.
 
seals

I personally wouldnt silicone it from the inside, chances are it wouldnt work and you just wasted alot of time pulling plastics and made a mess. You could use butyl tape not recommended but will work. I would pull the window and clean the old butyl tape off and use the black urethane sealant in a tube. Since your trading the car park it under something to keep it dry until you trade it, why put money and time in a car you're trading in??

Yes I am trading a buddy for another Mustang so if it is the rear quarters leaking I need to do a good repair. What would you guys recommend if just resealing the quarter windows? The exterior rubber is still in great shape.
 
Have you taken the back seat out yet, the bottom? Real easy if you haven't. If it's coming from the qtr window, then there WILL be a wet trail anywhere from the bottom of the b-pillar to the back corner of the seat bottom. If it was the door glass, the water would drip down the inside of the door and drain out the bottom, outside the car. Unless your run channel is REALLY cracked int he top corner and the rain was pouring down. I'd check the door seal with a hose first since that is easier than removing the interior plastic to seal the qtr glass. Open the door on the wet side and wipe dry the whole jamb/seal. Cloes the door and run the hose ariound the top and sides of the door seal for a few minutes. You will most likely be able to see where the water may be getting past the seal once you open the door to inspect from the inside.

You dont have a sunroof, do you?...not sure if it was an option in '93
 
Yes it does have a sun roof. It leaks from the hinges a little and the seal has hairline cracks around the whole seal. I plan on replacing that seal as well if I am going to order the other seals anyway.

The sunroof should have a drain with a tube that lets the water escape from the surrounding channel to the outside of the car. I'm not sure where this tube routes to, but possibly water is puddling at sunroof and dripping from there to the floor. Maybe someone can chime in on this. Sit inside the car and have someone run a hose on top of the car around the sunroof.

You're just going to have an elimination process with running water around al the seals until you find the culprit. And, NO I wouldn't recommend using silicone to fix the leak. Do it the right way

Ok I just pulled the seat and dry as a bone. I pulled carpet back and the piece that was tucked away under the plastic that runs directly below the quarter window where the seat belt runs is very dry.
 
Chances are, it's the sunroof drain tubes.

There are 4 drain tubes. 2 in the front and 2 in the rear. The rear ones go down the B-pillar and exit the body just behind the doors. If you look under the car, you will see the two small drain openings.

Usually the tubes crack or split or clog and leak.

SO really, you gotta pull the rear seat and rear quarter plastics and inspect. I bet if you poured water into the sunroof "moat" you might find the source of the leak with the panels removed

Ok now I know it's not a factory sunroof. I just pulled the lower rear quarter panel plastics on both sides and there is no drain hoses any where. Also I ruled out Quarter windows leaking because it's been raining like crazy and there is no water signs in that area its very dry. I pulled the carpet back in that area to see if it would have signs off the rain water coming in and nothing. Back seat frame rails also dry. The only thing I can think of is door to body molding is leaking what you think.

Instead of doing the round and round with us and since you have the trim panels and rear seat out get inside the car and have a buddy run a garden hose over the car, reall soak it and watch for water coming in. It might take a minute or two for it to work it's way in, if needed pull more stuff out of the way. lets us know what happens.
