project: Gangreen

[Berg]

Looks like a fun build, Love the SAS project by the way. Your back window not wanting to go up but works in the down position sounds like the tailgate side latches. They make sure the window only goes up when the gate is fully closed. Either fix the switch or jump it out and enjoy the luxury of a power tailgate window. If you notice the window only goes up 3/4 the way and stops its because the tailgate is pushed in and the window motor is catching on the metal glass channel keeping it from passing. It will go down but will catch on that part and not go all the way up. Simple fix is to sit inside the truck with your feet on the top of the gate and pull the inner structure back out with your hands. I recommend wearing gloves for this.
