Windscreen wiper motor and adjustment screw

Windscreen wiper motor and adjustment screw.

As I mentioned in a previous post, I replaced the windscreen wiper motor with one of the same model but from a Maserati. The problem arose when the blades did not return to their correct position and remained in a higher position. No one has been able to give me a solution to this problem, but yesterday a new mechanic I met took the motor apart and found a screw that regulates the starting and stopping position of the blades. Now runs perfect.

I'm letting you know in case anyone else has the same problem.

The bad news is that I had already bought some days ago a motor in perfect condition from a 612 on eBay Australia to replace my faulty one.

I'll keep it in case I need it in the future
