first of all, verify that the solenoid actually works, does the lever of the vacuum pod move?
if it does move, then some linkage is bent and needs to be hammered back in place.
if it doesn't move, first check the solenoid power. one wire in the connector is ground and one is positive.
first put both probes in the connector and check voltage. if it is 12v, then try another solenoid.
if it isn't getting 12v, then place one probe on any grounding point. other on the +ve in the connector.
if you then get 12 v, then one of the grounding wires in the wiring loom is disconnected. usually there is a thin wire on the gearbox that gets ground for that solenoid
