1969 corvette wiper problems
Hi everyone,
My new '69 Corvette has non-functioning wipers. I've been troubleshooting and have found the following:
However, when checking the 3-2-1 connector, I get bizarre results. I get +12V on the yellow wire. However, with the wiper switch in the "LO" position, instead of getting ground on the green wire, I get no connection at all. On the blue wire I get no connection. On the "HI" setting, I get 12V on the green wire and no connection on the blue. In the "OFF" position I get green grounded and Blue at 12V.
I'm not even sure what in the world is going on with that.
Best regards,
Matt
My new '69 Corvette has non-functioning wipers. I've been troubleshooting and have found the following:
- The wiper switch performs as desired and is grounded.
- The wiper over ride switch and the wiper door interlock switches behave as required.
- The wiper motor is getting power and is correctly grounded.
- The wiper door opens and closes correctly when the switch is actuated.
