Are you sure it is the solenoid?
The solenoid is driven by a power trigger circuit contained in the cap that connects to the solenoid easy to test by applying direct 12v to its 2 terminals. Should move if the coil is not open circuit or the solenoid armature is not stuck frozen.
Note the solenoid has 2 terminals and there are 3 wires going to the "white plastic cap".
inside is the electronic trigger which is repairable.
