I have a 1996 grand cherokee and the passenger door will not lock with the f
key fab or the switch on the doors. the only way to lock or unlock is to use the key or the manual slide switch on the passenger door. all other door locks and windows work properly. I have another parts jeep same year with all door locks working properly. Can someone tell me what I can swap so the door lock will operate properly

 

Welcome to CF. Check the rubber sock in the door jamb area for any broken wires. That's a common cause of that issue.
