This is a wiper motor for a Lapin HE21S. I heard information that it could be used on my old-spec Alto Works, and since my wipers were not working well recently, I bought it on Yahoo Auctions and tried to install it. However, the symptoms didn't change, and after investigating further, I found that the switch was faulty, so I no longer needed this motor. I checked the operation with a tester before installing it on the car body. I also confirmed its operation when installed on the car body, so I believe it can be used normally.
