The wipers on my cousins 69 Vette have not worked for some time. I said I would try to find out why.
Well, with the motor in the car I get 12v to the center pin (yellow wire) but nothing happens. There is a clicking when you put the switch on low. Like a relay is engaging. Took the motor out put 12v to the center pin nothing. Put 12v to right pin (low speed) motor turns wiper gear/cam counter clockwise one revolution then jams on parking mechanism. If you then touch the park wire (red pigtail) gear turns clockwise (high speed) to park position. I have bypast the wiper door limit switch which didn't help.
Any help on what else to check or what I may be missing would be greatly appreciated.
