moist, have checked everything in this area up to roof (hatch)
Suggestions would be appreciated

OK, my money is on the rear sunroof drain tube being disconnected. The carpet should be moist along the wheel hump too, but maybe it's dried out already. Check the seat bottom as well...it will absorb a lot of the water on it's way down. You may actually have more water in the car than you think! If the drain tube is disconnected, water will run down the C pillar behind the headliner trim and get absorbed into the carpet. Once the carpet gets saturated, it will puddle on the rear foot well.

Here are some pics from my recent adventure.

Also check the drain tubes under the hatch latch.
You'll have to unsnap the carpet, pull back to check if the tubes
are connected. If they are connected, it could have some blockage.
You'll need a 10mm to remove the lower portion to check if the tube is
blocked.

How odd that you brought this up. My daughter had my car for a couple of weeks, when she brought it back, she told me there was water behind the drivers seat. I soaked it up first, then checked all the sunroof tubes, all were connected and drained from the correct places. The only other thing i can think of is that there is a crack in the drain line somewhere. Got to do some more investigating. Keep me informed of what you find out. I will do the same.

+1 or is it 2 now, on the drain tube. They also clog and the end result is the same.

I used to have water leaking into that exact area.
Having blown out the drains and checked the tubes many times without fixing the problem, it finally dawned on me.

The seal around the sunroof panel is actually slightly higher on the outside of the removable roof than on the inside.
If the seal is not tightly fitted to the removable roof, water can collect in the channel of the seal and actually make it's way into the car interior and past the drain.
Here is a crude picture of what I'm talking about.

   

The low point around the seal is just over the floor in the back seat area. This was the only wet area in my car when it leaked.

My solution was to put a bit of silicone sealant onto the sunroof seal to attach it to the remavable roof panel with a water tight bond.
No more leak!

I've been leak free for at least 10 years now, and haven't had to unclog the drains once.

If your drains check out OK, check to see if the sunroof seal fits tightly.

Thanks Jamie. I did notice my seal was a bit loose where it joined at the rear and put a bit of silicone there. I dod not think about the seal being higher than the drain. Good catch.

Thanx Jamie. My car is always garaged and never taken out in the rain. I would have never known about the leak if not for the time I took it to RS Barn. Pete informed me of the clog and cleaned it out. But that didnt completely fix the problem. I bet your solution will take care of it for good.

Glad to help.
That leak drove me crazy for quite a while.

I had the same problem this year. Water in the back seat after a rain but only if it was a heavy rain or I parked a bit uphill. Back drain tube clogged. Bit of wire snaking and all fixed.

Excellent picture Jaime, gets the job done perfectly.



I had my sunroof hatch leak and it turned out to not be the drain tubes or the sunroof seal. I actually caulked up the drivers side rear drain as I could not get to where it leaked, but that didn't stop the lake in my back seat.



I doubled up on rubber seal between the body of the car and the roof right where it pinches. Worked for me.

that looks awfull. I think I have to chek it either. Good idea. Just in case.

just in time. I'll fixed it today. I had both problems. Due to the fact the car always stays outside it is important to check it. Now these cars are 20 years of age.

So I was looking today for some items I keep in the spare tire cubby space and discovered a mini-pond in there, approx about 3"- 4" deep. The entire trunk carpet is bone dry, both side cubbies are bone dry, everything that I can see and touch along the edges of the hatch is dry and there is no trace of water ever seeping through there, even the upper segment sides of the spare tire cubby hole are both dry, so how does that much water get in there... ??!! There are two rubber plugs at the bottom of the cubby and both seem fine and well sealed in place , so I'm trying to figure out what the heck is going on .. ?

Pour some water around the hatch pin receiver gaskets. You will probably find some gets in around the back of the gasket, then dribbles into the receiver but doesn't go down the hole and thru the tube. Instead it seeps though a small gap in the seal at the front then dribbles thru that seam behind the lights and into the wheel well. You could try new rubbers but I would suggest some strategically placed butyl or other sealant.

Hmm, interesting - will look into that, thanks .

As it turns out when I checked the seal around the pin receiver gaskets today I discovered that one was ok, but the other had not just a small, but a pretty big gap right where " dry968 " mentioned it might be. Used a silicon sealant to fill in that space, and hopefully that will solve that problem next time it rains. Thanks to dry, my car may stay dry :-) :-)

Interesting to know if this worked for you as I did this and thought it was fixed till it rained next time. Same leak??

I'll check it at the next rain ( though this is California, so who knows when that might be..) or the next car wash which will undoubtedly come first .
