At first they didn't work at all-- I quickly realized that it was missing the fuse so I bought one and plugged it in. The problem now is that when I turn the key so the car power comes on, the wipers turn on by themselves even with the wiper switch in the off position. If I play with the switch they eventually will shut off but typically when they're only halfway down the windshield. I have no idea what is causing this. I thought maybe the switch was sticking so I bought some silicone lubricant and sprayed it into the small areas I could and worked it in, but it didn't make a difference. Any thoughts?
When wipers get to the park position they hit a switch inside the motor body, if there is no power in that switch the wipers stop, if there is power they keep going. basically there are two switches, no power to the first switch means they stop if there is power then there is power to the other keep going switch.
There is a problem with the internal switches. That is why they only stop when the fuse is out or the switches work intermittently. I would say a new motor is needed or you can dismantle the wiper motor and try and fix the problem, you would see how they work anyway, quite clever and simple.
If I remember correctly there was a long court case in the '60s or '70s when the inventor figured his idea had been stolen from him, he won and got millions.
