I opened and cleaned the magnets ect in the motor, I've replaced the stick on the steering column with a new one, and I replaced the interval relay down near the left drivers foot. (My relay was full of rusty dust. The other rear relay looked fine.) Next I guess its trying to figure out how to read the voltage to the motor? Never taken a reading and I don't know if that is what comes next. Can a rear tail gate harness for the wiper play any sort of role in the problem? I'm working on replacing it after I get a hinge replaced. Any help would leave me grateful. Thanks
