I used the switch to let the bench seat down and when I tried to let it back up the switch was out.
The switch may have failed. I just looked at a wiring diagram. The system shares a common ground and a common power supply. Check fuse marked "Power Accessory CBA" 25 Amp in the fuse box. If the other seat functions work the switch is bad, something jammed in the seat or there is an electial/wiring problem.
