top leak
Sealing the drain slots on the lower window frame will cause problems. Since the window is a slider, water will work it's way into the lower track. There are actually two troughs that the water will drain from, one for the outer fixed glass, and one for the inner glass that slides.
I have seen a few different causes for these windows to leak, and testing with a garden hose is a great idea. Have the flow somewhat low, and someone on the inside to watch for the first sign of a leak. Start at the bottom, go from one side to the other, and then move progressively up.
The causes I've seen are;
Being parked on an incline (fore/aft) that forces all the water collected in the troughs to drain out of only one or two slots instead of all four (like pouring water into a funnel at a greater rate than what comes out of the bottom until it overflows at the top).
-The window slots not being "punched" thru all the way. Sometimes the inner track slot is not "open" enough to allow the water to drain.
-The lower interior screw in the center is not sealed. You'll see water dripping from the screw head.
-Screws were installed and then removed for the curtain slider rail, leaving an opening for the water to drain to the inside. If this is the case, the water may travel under the interior window frame edge some length before it drips, or it may soak the Ozite sidewall/headliner material below the window too.
-The opening for the window was cut larger than it should have been, exposing an opening that the window seal is not sealing. Usually a good RTV sealant will work if this is the case.
-There is a small plastic trim that clips to the inner edge of the trough that supposedly helps keep the water from overflowing. It is usually loose at the ends and not that effective, especially if the drains are working properly and you are parked fairly level.
I hope this helps!
