Liftgate glass goes down when u turn ign.key off.

There's either a short in the wiring or a stuck switch. Should probably take it to someone to get diagnosed. In the mean time, have you tried raising the window with the key trick? That is, with the vehicle off, you can insert your key into the tailgate lock and turn/hold it to the lock position to raise the window. Again, you should have someone take a look at it! http://repairpal.com/toyota-within-10-miles-of-hico-texas-76457
