Thank you for the link Art! I have purchased a test light since my last visit to the brickboard page, I also have a volt meter as well.

1)"What I'm asking you to probe is easily accessible from the same position you would contort yourself into lubing the right hinge pivots on your hood. You want to make contact with the probe of your test light or meter, to the exposed smidgin of metal inside the plug at the termination of the harness wire. If you measure between ground (use the braided wire or clip onto a strut mount stud) and the two aforementioned wires, you can determine whether the power gets interrupted to the motor.

The yellow wire should have power always. 12V is just another word for battery voltage, and a synonym, in this context for power. Use that as a reference for your probe test. The green and brown wires (from memory) have power on them when the wiper is wiping, in fast and slow mode respectively."

So to test the power to the motor I need to stick my probe into the wiring harness of the motor making contact with the yellow wire while grounding it to my strut mount. Then I need to test the green and brown wire the same way while initiating the slow and fast speeds of my wipers.


2) "the relays all will develop crack around the larger through-hole components on their circuit board wave soldering."

I did notice a small crack on my relay circuit board to the left of the copper wire wheel, it appears to me to be a grounding wire coming off the wheel maybe? The relay does click when I turn the ignition key, but from what I have heard that doesnt mean that the relay is actually working properly, right? I didn't notice any other faults on the circuit board except a discolored solder, but I checked the continuity along that particular solders line and it appeared to be flowing properly.

3) I am also going to pull the motor off again and clean around the grounding bolt and apply some anti-corrosion lubricant just to be sure.

Thanks again for taking the time to help me trouble shoot my wipers!
