There is no testing for the WCM - you test the MFS, the wiper & spray motors, and the wiring. Testing Diagram & Instructions in 92-96 ".

Multi-Function Switch (MFS) Cleaning "Just hit hazard switch in and out for about a minture, which cleans the MFS contacts and presto" Is that right? Is there anything else I should check for in the wiring? Other than the relay, is there any kind of fuse for the wiper motor? I didn't see one? I'm stumped. Guessing I need to put the black lead on the ground, and the red lead on the green. So, why isn't the new motor working, and how can I check that it's getting the proper voltage. problem was, the motor would run when I turned the ignition on and I couldn't control the speed or shut it of. The strange part is before I went back to the two plug motor, I had found a single plug style and was able to get it to work. Long story short, I cut the connector and everything off my old harness and spliced into my new harness.the wire colors were exactly the same so it was easy.got everything hooked back up and turn the wiper on, nothing.I can hear the click from the wiper control module when I rotate the switch, but the motor doesn't turn on at all. my old harness had two.any way, after looking all around town for a single plug motor, I wound up switching back to the two plug. When I installed my MAF harness, there was only a single connector for the wiper motor.
