So... my two year old was playing in the truck, and I'm used to afterwards the wipers being on, etc. We get in the truck and head off with both driver's side windows and the rear liftgate window down. We get where we're going, and the liftgate window won't roll up with the switch. It rolled up fine with the switch. Side windows rolled up fine. We get back home, and I go into full Engineer troubleshooting mode. Not a fuse, since the rear keyswitch works fine, right? I think maybe my son pushed on it, and there's a connection issue, so I disassemble the console to inspect the switch, I've done a few times and it really just takes a minute. Of course, no problem with the switch. Then it dawns on me... what else would interrupt the switch? The damn window lock is on (thanks, Junior!). Who would have thought the switch would interrupt the rear window? Not me. Thought I'd share as another one of those "a-ha's". By the way, the window lock does NOT affect the sunroof...
