I need some help.... I have rewire my truck and added an alternator. I used everything I could get from MAD. I am still working out some small kinks but I cannot get my wipers to work. There is power (12v) to them and when I turn the switch to the off position and hold in the button on the motor the wipers will operate. When I release the button they go to park. New switch and rebuilt motor. Any Ideas? Thanks in advance....Jeff
