1. Remove switch from door trim panel.
2. Carefully separate multiple terminal block on wiring harness from switch body.
3. Connect one lead of test light to a ground terminal:
- Touch other test light lead to battery feed B+ terminal.
- If test light comes on, the wiring circuit between the battery and switch is functional.
- If test light does not come on, check for a blown fuse. Refer to Wiring Diagrams for circuit information.

NOTE: Vehicles equipped with the auto-express feature for power windows, the local interface network (LIN) controls the lock, mirror and window features.

Remove the non-express switch from its mounting location. Using an ohmmeter, refer to the DOOR LOCK SWITCH CONTINUITY table to determine if the continuity is correct in the LOCK and UNLOCK switch positions. If these results are not obtained, replace the switch.
