Vaccum switch under the battery moves the trans cable and holds it engaged when pressing selector switch yet no 4 wheel engagement.

I can hear module under rigth side kick panel working and the lights on the selector switch indicate engagement.

Could it still be the vaccum switch on the transfer case?
