The actuator has given problems before but I just reoriented the gear away from the crack. It worked for a while but eventually slipped to a position that quit again.
The new part came in and I replaced it. I once found a procedure for diagnostics or calibration but can’t find it today. Looks like pulling the fuse long enough to reset the AC control module will do it.
Looks like it is fuse 28 in the glove box fuse panel.
