Wiring Voltage Test
The following wiring test determines whether or not voltage is continuous through the body harness to the front switch.
- Remove the power window switch and bezel.
- Disconnect wire connector from back of power window switch.
- Switch ignition to the ON position.
- Connect the clip end of a 12 volt test light to Pin 4 of the window switch harness connector. Touch the test light probe to Pin 3.
- If the test light illuminates, the wiring circuit between the battery and switch is OK.
- If the lamp does not illuminate, first check 30 amp circuit breaker in the fuse block. If circuit breaker is OK, then check for a broken wire.
