My 1997 S15 Jimmy is a wet mess on the passenger side after a rain. I am pretty sure the rain is running down the inside of the door where the seal that is attached to the upper part of the door frame has been coming apart. I see water in the door seal at the threshold. Water appears to be flooding across the threshold after it runs down the inside of the door, into the inner gasket and then floods onto the floor. That is not the case on the driver's side where the roof/door seal is intact That threshold gasket is dry. Both inner door gaskets are in good shape other than a small gap near middle of threshold which I figure is age shrinkage.

It is not my heater core (new) or does it appear to be migrating from a front kick panel. I recently replaced the regulator in that door and checked drains as well as the inner lining, so I am pretty sure this is not leaking from inside the door.

Any ideas on the proper GM part which I can use to cross-reference?

Thanks in advance!

Thanks,
I did find that site, but like all others, the thin gasket that is attached to the inner, top edge of the door (inside the window frame), is not clearly defined.

In any case, my flooding issue was resolved by removing what was left of the gasket. Apparently a small piece of that gasket was acting like a hose, funneling water off the top of the door, directly onto the passenger floor rug. Since removed, no water!
