Trouble Shooting

Check all fuses before beginning any testing. Check terminal contact before replacing any component.
If only one lock motor does not operate, check wiring for an open or short circuit. Repair or replace wiring as necessary. If door locks operate from transmitter, but not from door lock switches, check continuity of door lock switch and associated wiring for an open circuit. Repair or replace wiring as necessary.
If only one transmitter does not operate, check and replace batteries in transmitter as necessary. If transmitter still does not operate, replace transmitter and program keyless entry module.
