Default Water leaking into car

Water is leaking into 96 SSEi from somewhere. It collects on floor of rear drivers side. How do I fix this?

Do a search on leaks. Your problem is probably having to do with the sunroof drains leaking inside the car. You can test it by pouring just enough water over the sunroof for it to drain and not runoff over the paint. Then watch and see where it drains, if it does at all. That should lead you somewhere. But do a search for sure, this has been discussed many times.

Here is a recent water leak thread with links to another. It should get you started in the right direction at the least. Holler if we can help.

jv:
Let me know if I can be of any assistance on this. I had a heck of a time with this very problem. Check your sun roof drains. I'll bet you one or two (maybe all 4?) are disconnected. You can drop the headliner in the rear enough to access them.

Let me know how it goes.

A quick sign of the sunroof drains being the issue is if the headliner is wet in the back corners. AFAIK the only connection in the lines is up above the headliner.

It has been too cold and dry of late for the problem to reproduce.

However, this morning both driver'* side doors were stuck.

When I eventually got them open, I found ice was the culprit. It had gathered along the bottom seals and along the lower front door seal.

The passenger side doors were dry.

Does this suggest driver'* side door seals are leaking?

Check to see if the seals are pulled tight in spots. Over time, they will shrink and pull away from the "sharper" bends of our door frames.
If so, you will have to peel them up and re-apply, leaving a gap in the bottom of the door frame. This gap can be filled with a donor piece from the junk yard. (See link Boosty supplied above)

Most likely, water is leaking down the headliner from un-plugged drain tubes and going for a ride along the seals and settling in there.

The fact that you have water behind the front seat, on the floor pan makes me think the rear drain tubes are unplugged.
You need to get in there and see what is happening.

Please let us know of your findings.
