Leak in 87 300TD - wet 3rd row seat

Hi All,

On Sunday I drove home through a pouring rainstorm. Tuesday when I folded up my 3rd row seats for the kids, the carpet under the seat was damp and there was water on the surface of the seat.

The car has been sitting out in a rainstorm before and I didn't see any dampness. Could there be a leak underneath somewhere and the water came through because I was driving? Where should I check?

Maybe the rear glass, or the hatch seal. It could also be the rear quarter windows. Get it dry and stick one of the kids inside and do the garden hose test. Hopefully that will pinpoint it. If it is the glass it can be caulked, if it is the hatch, it may need to be adjusted or the gasket is worn out.

Greetings from the East End.

sounds like it is coming from underneath somewhere. check your body drains, and the wheel wells.

good luck....

I have a random leak coming from my rear hatch window seal. It doesn't leak on a regular rainstorm, just leaks when its windy and raining at the same time.

To track the water path, I removed the carpeted panel on the rear hatch but then got distracted on another project. Funny thing is that ever since that rear panel has been removed, the rear of my wagon has since stayed dry for the last 6 months.

When I have time, I'm going to take my wagon to my window guy, and he can use a syringe and squirt some kind of sealant into the window seals.

Check the seal on the fuel filler neck also. If water is getting in there it will go to the wheel well and possibly migrate to the seat well. Just a thought.

I found water getting in around the aerial seal.
Another area to check is where the gas struts go through the rubber bellows type seals.
