Manually roll up power window

sure, take off door car
access motor,. and remove motor or find a way to move its gear
drive to put window up
or hot wire motor. (one way goes down, other polarity up)
ask for how to hot wire, (do so connector at motor pulled)
use a jumper wire with 15amp inline fuse #18 gage wire or larger.

you have a broken wire on the harness that goes thru the driver door

The Window that only rolls part way down, the stop for low position has moved apparently and must be manually reset. The other that won't move at all, your correct in checking the power to it. Pull the panels to access them.

If you have a multimeter you can go to the underside of the master panel in the drivers door and independently check the switches for voltage or with no power to the switch assembly check for continuity. Good place to start. If you get continuity to through the switch then you need to check power to the window actuators in the doors.

check for power at that window motor plug behind door panel while operating window switch. No power? replace window switch. Have power? replace motor.

REPLACE THE POWER WINDOW SWITCH

thats cause that what the lock is for so it wont go down

be careful with jeeps they have a body control module that controls the windows , locks ect they go out often a dealer with scanner can check. also you have the window switch on the drivers door , rarely is it the regulator on a jeep

If you have power windows it should be a broken cable, If its manual then it should be the crank asm. or the white plastic trac, it may torn at the end.

most of the time it is wires in the drivers door that break in the loom
