Rear window not working

Checked fuses and relay, read other related problems. Mine will not work at all, no noise, no anything. If I pull the fuse out and wait a few seconds then re-install the fuse, the window will release and open. If I close the window and push either the inside or outside release button, nothing. If I remove then reinstall fuse, it will release. I also unplugged the wire from the release motor then plugged it back in and it worked. But neither button will release it. Unplugged and plugged wires into motor several times and the movement seemed to get weaker.

Hello,

It sounds like the window motor is going out. T be sure lets check for 12 volts at the motor to confirm the failure. here is a guide to help and the window wiring diagrams below:

Thank you Ken. My issue is with the rear window, over the tailgate. Having trouble with the release working so it can be opened. Any chance you have a diagram for that? Thank you for your time.

In the under hood fuse panel there is a fuse and a relay I would check. here is a guide to help check the relay with the fuse and relay locations and the wiring diagrams as requested:
