Blend door motor

[Aceofspades]

So I removed it - the motor works in it however , after the shaft spins it just ticks back and forth once it gets to one end. It stays ticking

Any idea what's up?

Ok. So for whatever reason this little module is quite annoying. Now it seems to be working. Lucky for me I cut an access hole to it so I only need to remove glove box and air bag if and when it acts up again.
