Power Window Switch: Testing and Inspection
1. Test the master switch as follows:
a. Remove the switch from its mounting. Turn the ignition switch to the "ON" position. Leave the wiring harness connected to the switch and connect
a test light between the TN wire and BK wire.
^
If the test light does not come on or is dim, check the circuit breaker and the wiring to the switch.
^
If the test light comes on, go to step 1b.
b. Move the master switch through all window positions and check for power available at the proper wire terminals:
LB left up
WT left down
BR right up
VT right down
^
If the power output from the master switch is incorrect, the master switch is defective.
