CONTROL SWITCH
Disconnect control switch 6-pin connector. Disconnect 2-pin connector at each seat motor. Check continuity between specified terminal of control switch connector and specified terminal of motor connector with control switch in specified position. See CONTROL SWITCH CONTINUITY TEST table. (Scheme 3) If continuity does not exist between terminals as specified, replace control switch.

CONTROL SWITCH CONTINUITY TEST
Scheme 3
MOTOR
Disconnect motor 2-pin connector. Apply battery voltage and ground across motor connector terminals. Reverse polarity to move seat in opposite direction. If motor does not operate, replace motor.
ALL FUNCTIONS INOPERATIVE
- Check POWER SEAT fuse. If fuse is blown, replace fuse (repair circuit if shorted). If fuse is okay, measure voltage at Yellow wire terminal of control switch 6-pin connector.
- If battery voltage is not present, repair Yellow wire between POWER SEAT fuse and control switch. If battery voltage is present, disconnect control switch connector. Check continuity between ground and Black wire terminal of control switch connector. If continuity does not exist, repair Black wire between ground and control switch.
- If continuity exists, reconnect control switch connector. Measure voltage at wire terminals of specified motor connector with control switch in specified position. See VOLTAGE TEST table.
- If battery voltage is present at all wire terminals of all motor connectors, replace control switch. If voltage is not present at any wire terminal of any motor connector, check control switch. See CONTROL SWITCH TEST under COMPONENT TESTING.
- If control switch is okay, check for open circuit between control switch and motor. If circuits are okay, check motor. See MOTOR TEST under COMPONENT TESTING.
| Switch Position | Wire Terminal | |
|---|---|---|
| Front Lift | ||
| Down | Red/White | |
| Up | Red | |
| Rear Lift | ||
| Down | Yellow | |
| Up | Yellow/Red | |
| Slide | ||
| Backward | Green | |
| Forward | Green/White | |
VOLTAGE TEST
ONE FUNCTION INOPERATIVE
- Measure voltage at wire terminals of specified motor connector with control switch in specified position. See VOLTAGE TEST table. If battery voltage is present at both terminals of specified motor being tested, check motor. See MOTOR TEST under COMPONENT TESTING.
- If battery voltage is not present, check continuity of wiring between control switch and motor. If continuity does not exist, repair wiring between control switch and motor. If continuity exists, replace control switch.
