1. Remove the power lock switch from the door inside trim panel. Refer to SWITCH, LOCK, REMOVAL .
2. Disconnect the door wire harness connector from the back of the lock switch.
3. Using an ohmmeter, test the resistance between the terminals of the switch as shown in the Power Lock Switch Tests table.

   POWER LOCK SWITCH TESTS
   SWITCH POSITION (PINS)	*RESISTANCE (OHMS)
   NEUTRAL (2 and 3)	50 Kilohms
   LOCK (2 and 3)	1 Kilohm
   UNLOCK (2 and 3)	249 Ohms
   SWITCH ILLUMINATION (1 and 3)	LEDs - SET MULTIMETER TO DIODE MODE - CONNECT PIN 1 TO PLUS (+), CONNECT PIN 3 TO MINUS (-) - LED SHOULD BARELY GLOW
   *All resistance values are plus or minus 5%.

4. If the switch fails any of the tests, replace the ineffective power lock switch as required.
