Rear Wiper Problems 99Navigator
Rear wiper is not working. Went to the junkyard and pulled off two more. Installed both, but none of them seem to be working.
I checked the wiring at the motor. There are four wires there. It gets 12V on the one set of wires (main power?). But I can't seem to get any response from the other set of wires, even while turning the wiper switch on/off multiple times.
I see that there are two relays. Neither one is clicking. I bench-tested them both, and they passed. I see that there is one rear wiper fuse and it looks good.
So, it seems like there might be a problem with the rear wiper switch? How can I test this to verify that it's the switch? Can I somehow send a signal to the motor just to verify that the motor works?
