Just installed weathertech on my wife's '99. Had the same difficulties you guys are experiencing. Called weathertech they said install the ill fitting passenger side one with the window down about 2 inches, then roll it up and leave it for two days. It still did not really go all the way up, so I pulled the unit out a tad and retried the window and it rolled up all the way and been working fine since. Yes, I use alot of spray silicone on my channels, though. Also, it only takes about five minutes to remove the door pannel. Just follow the service manual instructions. The manual is on Tone Monday's site if you don't have one.
