So I've spent the last few months all over the place trying to find this info so now I bring it here.
I have a 2001 galant and currently have no control over my wipers. I've swapped out the switch and still nothing but haven't tried the motor yet.
Basically it is always on, the only way to turn it off is to disconnect the motors power supply.
Also when it gets too wet the radio wont turn off when I turn off the car.
