my 93 does the same thing, it also floods my trunk! I believe I narrowed it down to the rear window seal, it seams to be leaking at the bottom of the rear window. I would guess you could take it in and have someone reseal the window, if not then it will have to be pulled and then resealed! i haven't tempted it yet.
I had the same problem. If you have a sunroof, there are four drain holes inside each corner of the sunroof. If one of them becomes clogged or disconnected it can cause this. If disconnected, you will have to drop the headliner to access the drain tubes or reconnect them. Hope this Helps!
