TJ hardtop rear window leak - solution?

My rear window in my '03 TJ leaks. I've repositioned the window to see if I can tighten it up but to no avail. I get water seemingly leaking in at the bottom corners and (this is where it gets weird) seemingly defying gravity and running back up and over the rear lip at each bottom corner of the window and back into the outside back corners of the tub. Essentially, I think I need new seals on the whole roof. But this isn't an option right now. I need another type of temp. fix.

It's not a huge deal. Nothing's getting wrecked because I'm putting towels down in the back corners that soak the water up. But after a rainy night, I have to wring every bit of water out of a large bathroom sized hand towel. And I live in Wetcouver. Literally a rain forest, so this is a common occurrence. I know at this point people are probably reading this and saying "use the search function". Yep...tried that. Lots of threads with the words "leak", "water", "hardtop", etc., but none seem to address my problem specifically.

So here's what I'm thinking may be a solution. I was going to lay a bead of caulk from about 3 inches forward along each side of the tub, back towards the inside of the tub, then back in a line to the rear window. Each bead would come back to meet at the rear corner where the window meets the tub. Picture an upside down and backwards L for the drivers side and just an upside down L for the pass. side. This way, I'm covering about 8-10 sq. inches of surface that the towels usually cover that rain could collect and not flow anywhere because of the bead of caulk. Then, I was planning on drilling a small hole through the tub to have an area that the water can drain from.

The "drain hole" is where my question really lays for you informed folk. Is there anything directly beneath the rear corners that would prevent me from drilling a small hole through the tub so that water would drain? If the hole would be fine, would the water be draining on anything I don't want it draining onto? I know the EVAP canister is on the pass. side, but water hits that all the time with just regular driving. Tail light wiring? Other? I've looked the best I can and it seems ok, but is there anything hidden that I may be missing?

Thoughts? Ideas? Personal experience?

I think you're on the wrong track.
First, assuming your top window weatherseal and tailgate weatherstrips (A and B in the pic) are in good shape.
Look closely at the hardtop the end of the rear window weatherseal, at the bottom on each side, where the top meets the tub and seal ends. (C in the pic)
Notice how the top has a little 'ledge' molded in, and the seal stops at the ledge.
Water runs off around the window seal, down to that ledge, and puddles. It then finds its way in where the seal is snapped in place.
A very small bit of silicone - sealing the weatherseal to the 'ledge' - forces the water to run out the back rather than seeping through the crack.

The Jeep's in the shop getting my rear shocks outboarded, but as soon as it's back, I'll take a look at A, B and C to see what the condition is.

If it makes any difference to your thoughts, this doesn't happen when I have the soft-top on. Only the hard-top. So I think you may be onto something about the seals.

P.S. - Interesting file/pic sharing program. I've never seen it before. I kinda like it!

same thing happens to mine. i realized it with all the rain we're getting in new england. i think my problem is with the seals. also, water seems to be leaking in at one of the bolts that holds the hardtop to the tub. it seems like the water is going between the tub and the hardtop and getting thru.

You're from the Valley, so close to me. So where'd you buy the silicone spray? Lordco? Canadian Crap? Other? What brand?

this is just an idea to go along with your drilling holes for draining idea

you drill small holes and then these pieces drop in the holes and direct the water out. put a dab of sealant around the hole to keep these in place. i've actually got them on my vette so i can take a pic tomorrow if it seems like an option you may be interested in.

Any autoparts store . Aerosol can that says "silicone" on it. Most shops use it to lubricate window tracks. Helps sticky windows and weak motors!

I know your pain too well. Being just across the channel I face the same weather and all winter my back window leaks. I'm interested to see how you fix yours, I just parked my jeep facing uphill all winter till I put the soft top on, and that is clearly not a solution.

I am interested, but can't figure how they'd work by looking at the eBay pics. Could you photoshop some Vette pics and post them for us all to see?

But the other questions: is there anything directly under the tub corners to interfere with a small hole being drilled (besides the evap. canister on the pass. side)?

Uphill parking is no worse or better for me if that says anything for my problem.

follow the arrows on the pictures. from the furthest out picture you can see how the natural lines of the car lead to water pooling up in that corner. i dont drive it in the rain, so thats not the problem. the problem happens when i wash it. all of the water pools up right there and then as soon as you think the whole car is dry...dribble dribble dribble, the water slides down the side of the car and its just frustrating. i drilled a hole, dropped the tube right in and now all of that water drips out of the car. i would get some pictures from underneath but you get the idea- dont hit anything with the drill and make sure its not leaking onto anything essential.

Thanks. Your Vette idea might have to be a solution if silicone and such don't fix it.
