The real problem is that the previous owner stripped the plug off of both the motor and the wiring harness. I think but I'm not sure there is a problem with the wiring harness to the wiper motor. What I am trying to validate is how does the motor actually work and then what is wrong with the harness.

Is there a way to bench test a wiper motor to see if it is working? I was thinking that using the battery, I could apply power to the LR (Power Source) and a ground back to the battery via B (Ground) but what do I do about the LW (To Relay), L (Low) and LY (High). I assume that they are some how related to the 2 or 3 speeds of the motor. If anyone knows how to do this I would appreciate the help. r/, Jimmy
