Yeah its the motor itself, inside the motor its like a clutch almost. Its got a rubber outer ring which is worn and is slipping.
Took me a while to get it out and im pretty sure its going to take me even longer to put another one back in.
Once the trim is off, i dont see any other way other than sliding everything up through the top (correct me if im wrong).
If anyone can help me on this it would be awsome!
Thanks,
