DOOR LOCK SWITCH
DIAGNOSIS AND TESTING - DOOR LOCK SWITCH
1. Remove the switch.
2. Using an ohmmeter, refer to Door Lock Switch Test table to determine if switch resistance is correct in the Lock
and Unlock switch positions. Refer to Wiring Diagrams for harness connector pin-outs.

DOOR LOCK MOTOR
DESCRIPTION
The lock mechanisms are actuated by a reversible electric motor mounted within each door and tailgate. The power
lock motors are integral to the door latch units.
The power lock motors cannot be adjusted or repaired and, if inoperative or damaged, the door latch unit must be
replaced.
OPERATION
The door lock motors are controlled by relays. A positive and negative battery connection to the two motor terminals
will cause the motor to move in one direction. Reversing the current will cause the motor to move in the opposite
direction.
DIAGNOSIS AND TESTING - DOOR LOCK MOTOR
The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a scan tool
and the proper Diagnostic Procedures manual.
Refer to the appropriate wiring information.
1. Make certain battery is in normal condition and fuses powering the RKE module aren’t blown before circuits are
tested.
2. To determine which motor is inoperative, check each individual door for electrical lock and unlock or disconnect
the motor connectors one at a time, while operating the door lock switch.
3. In the event that none of the motors work, the problem maybe caused by a shorted motor, a bad switch or a bad
relay internal to the RKE module. Disconnecting a defective motor will allow the others to work.
4. To test an individual door lock motor, disconnect the electrical connector from the motor.
5. To lock the door, connect a 12 volt power source to one pin of the lock motor and a ground wire to the other pin.
6. To unlock the door, reverse the wire connections at the motor pin terminals.
7. If these results are NOT obtained, replace the motor.
