Hello all,
I'm having trouble with a '72 Cuda 2-speed wiper motor. Car has a new wiring harness and I'm troubleshooting someone elses wiring job. Its a new American Autowire and everything looks okay. Nothing worked when I started but I fixed some wiring issues and the grounds and I now have LOW and HIGH but no park. It appears the blue PARK wire should be at 12 volts with the switch off and it tests correct right at the motor. I'm also assuming that the motor uses the ground at the firewall to park since the green wire from the switch is only grounded in HI and LOW positions. I have 12 volts (+) between the blue at the motor and the motor itself but still doesn't park. I have also confirmed I have a 2-speed switch and a 2-speed motor. Here are the wires that I have:
WHITE (at switch only) = 12 volts with key on
BROWN = LOW
RED = HIGH
BLUE = PARK (12 volts with switch in the OFF position)
GREEN = Ground for Low and High speeds (grounds through switch body in the HI and LOW positions)
I haven't worked on many Mopars compared to others. Any help on what to look for next would be appreciated.
Thank you,
