Water leak

On my 98 Tahoe I have the rear tailgate style back door and I have an extream water leak some place. I have had the rear tailgate and glass gasgets changed by the chevy dealer thinking that was the problem. The headliner is not wet and neither is the fabric on the back of the tailgate. Only part that is wet is the right rear floor and it is soaked. I have the rear a/c and the stuff for it is right near the leak but I dont think it is that leaking cause it only occurs when it rains not when I have the rear a/c on. Any ideas on were the water is comeing from? this is a huge problem for me because it just made a 500 dollor amp useless. Please help

have you checked your window rubber for your side windows? could be leaking down under it then coming down the side of the panels. also check to see if the drain plug in thef loor on that side is still there.

all the plugs are still in the floor. should I have a window guy look at the window?

get a friend to set inside the tahoe while u pore water over the back door with a water hose and just look for the leak
