Re: 66 SS wiper motor problems
OK, after much hand wringing, bench testing the motor, bench testing the switch, and crying, I finally figured it out. Not sure how it happened but the black high speed ground wire is connected to the switch as the washer ground. And the Dark blue washer ground was run to the high speed side of the motor. I finally realized this when checking continuity to ground at the wiper motor. So I switched them and everything works fine. I may have scrwed this up at the switch, when I wired the dash, or at the front motor harness when I removed the electric oil pressure wire, not sure. The answer was here on this site but I obviously had to keep looking for the solution.
