I pull the lower switch and short the pins on the connector it raises but doesnt lower. I switched the connectors on top of the solenoid and it still doesnt lower. Its the single on_off switch.

It depends on how the sensors in the head are set. If the head raise and ground drops out from under the header it will lower like going over a bump.
