All Functions Inoperative
- Check fuse. If fuse is blown, replace fuse (repair circuit if shorted). If fuse is okay, measure voltage at Yellow wire terminal of power seat main harness connector under seat.
- If no voltage is present, repair Yellow wire. If battery voltage is present, check continuity between ground and Black wire terminal of power seat main harness connector. If there is no continuity, repair Black wire. If there is continuity, check for open circuit between control switch and motors. If circuits are okay, replace control switch.
