Have seen a few repair videos of other manufacturer's mechanisms with a failed internal motor/worm drive. Inexpensive to repair but getting access varies considerably.The actuator is part of the door lock so I can’t see how you’d make them work.
I’d be interested to open a faulty lock mechanism and see what actually wears out, then see about repairing it
The internals of a Toyota Lexus mechanism. Not saying it is the same as a Maser, but would think it would be similar. The replacement motor is a couple of dollars.Unfortunately no. I already check with them, scuderia and few other vendors non of them has it.
