Test F: Driver's Power Window Inoperative (2-Door)
- Turn ignition ON. Observe LEDs on both power door control switches. If LEDs illuminate, go to next step. If LEDs do not illuminate, go to step 5.
- Remove drivers power window control switch. See POWER WINDOW CONTROL SWITCH under REMOVAL & INSTALLATION. Test drivers power window control switch. See DRIVER'S POWER WINDOW CONTROL SWITCH (2-DOOR) under COMPONENT TESTS. If switch is okay, go to next step. If switch is faulty, replace switch and test system operation.
- Turn ignition OFF. Disconnect drivers power window motor connector C782. Measure resistance between C782 terminal No. 1 (Yellow wire) and ground. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open or high resistance in Yellow wire and test system operation.
- Turn ignition ON. Push DOWN on drivers power window control switch. Measure voltage between C782 terminal No. 2 (White wire) and ground. If battery voltage is present, replace drivers power window motor and test system operation. If battery voltage is not present, repair open or high resistance in White wire and test system operation.
- Turn ignition OFF. Disconnect drivers power window control switch connector C488. Measure resistance between C488 terminal No. 1 (Black wire) and ground. See Figure. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open or high resistance in Black wire and test system operation.
- Measure the voltage between C488 terminal No. 10 (Green/Blue wire) and ground. See Figure. If battery voltage is present, wiring is okay, verify customers concern. If battery voltage is not present, repair open or high resistance in Green/Blue wire and test system operation.
