Check and confirm the wiring is correct




It works now, wiring was ok, it was a problem with spring contact in motor cam, it was open all the time and motor didn't have power to park

Make sure your dash switch has a good ground





How should it be grounded? there are two tabs that hang free "in the air", one with heater lamp attached - has small screw hole at the end, second on the door side with 1/4" hole.
I checked and it had ground, but to make sure I added self made wire from one tab to dash frame
