Sorry this is a double post but I've only got one reply in the troubleshooting section since I posted nearly a week ago. I just need to know how to troubleshoot my wiper motor. I bought a new unit from ground up then after installing it I turned my keys on and the wiper blades went from all the way down to all the way up then stopped. They haven't moved from there since and I've tried wiring the wiper switch all different ways but that hasn't done anything. I'm pretty sure the wiring on the motor itself is correct because my old motor worked for a while after I rewired my car. Where should I be checking for power when the switch is on? It's a 70 without hideaway wipers.
