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.
