Test C: Driver's Power Window Inoperative
- Turn ignition switch to LOCK position. Disconnect driver's window motor 2-pin harness connector. Turn ignition switch to RUN position. Measure voltage between power window motor harness connector White/Black wire and Red wire terminals, while operating master window/door lock/unlock switch. If voltage is less than 10 volts while operating master window/door lock/unlock switch, go to next step. If voltage is 10 volts or more while operating master window/door lock/unlock switch, replace driver's window motor.
- Turn ignition switch to LOCK position. Disconnect master window/door lock/unlock switch 12-pin harness connector. Measure resistance of White/Black wire between master window/door lock/unlock switch harness connector terminal No. 4 and driver's window motor harness connector terminal. See Figure . Measure resistance of Red wire between master window/door lock/unlock switch harness connector terminal No. 9 and driver's widow motor harness connector terminal. If both resistances are less than 5 ohms, go to next step. If either resistance is 5 ohms or more, repair open in White/Black wire or Red wire.
- Measure resistance between ground and driver's motor harness connector White/Black wire and Red wire terminals. If both resistances are 10 k/ohms or more, replace master window/door lock/unlock switch. If either resistance is less than 10 k/ohms, repair short to ground in White/Black wire or Red wire.
