I will only add that I have a random WS gasket leak. If my truck is sitting in a parking lot in a gentle rainstorm, the driver's side WS corner will leak quite a bit. If I'm driving down the highway in a blinding rainstorm, it won't leak. I had a glass guy attempt to re-seal, but the real solution is to replace the WS gasket. Plenty of threads in this forum on the challenges of installing a leak-free WS. Hope you find your leak - it may take a while!
