recently my windshield wiper motor stopped working so i went and ordered another without really testing the original to check if it was just a short....today i put the new motor in and it didnt work...it was grounded good but no matter what terminal i put juice to it doesnt move...i was thinking that the problem might be the switch, does anyone here know if the switch reduces or does something to the current? plz reply it would be most appreciated thx : )
