I have a 2000 Cherokee and the driver is the only one who can roll windows up or down also power lock doesn't work

 

check wiring at driver door frame and research the power lock fix

 

Simple fix - do a search. You will be jumping the tan and yellow wire in the lower driver's side kick panel. Many threads on this.

 

Extremely common problem, probably in the 90% range.

Window lock button shorts out, locking out the passenger door window switches.

Quick fix: Use a paper clip to bridge the connection for the yellow and tan wires hidden under the trim piece to the left of your left foot.

Right fix: Replace the wires.
