Thanks for the reply

It just seems really stiff?? I have 3 the same and none of them want to move very far.. Also it seems like the plastic ring around the edge is stopping it. None of them spring back either?

Also tried Ford, and even a technician didn't know how it worked which I thought was a bit ridiculous to be honest. Tried turning a new one there and it wouldn't budge either!

Any more info?
