If it fails to the point of the top "not moving" then there will be a stored fault code for the reason it stopped moving. It doesn't just stop without a reason. The mechanic has to check for STORED fault codes. Or you can also bring it to the shop when the top is in the failed state, just give them a call and let them know it's doing it NOW and you're bringing it in.
