heating control

Evening folks,

hope everyone is okay, bloody cold now here in the North East of Scotland!

I have managed to remove one of the screws holding on the passenger side
bend motor. I have moved it off the cog and have tried moving it by hand.
Nothing is happening. Should I be able to move the cog by hand or is the gearing too high?? Also I take it it should move as I raise and lower the
temperature using the hvac controls, no??

Any tips would be gratefully received as I have tried the usual suspects and
just want to confirm it is this before ordering a new one,

Thanks again.

Drew.
P,s any tips on getting the glove box out? Is it just the row of screw on the top then the bolts for the hinges??
