Power Door Locks
 

I have a 2001 Jeep Cherokee Classic. when I hit the door lock button on driver's side the drivers side and rear door work fine but neither the passengers front or rear doors will lock or unlock when pushing the button

The switches for those two doors may be at fault, you may want to get replacements from a junkyard. I'd get replacements for all four doors.

Did you check for broken wires in the door rubber booth's. mine had a broken wire and i figured out after replacing the window switch. Good thing is now i have got a new switch.
