The wiper motor on my 72 El Camino does not look like the other 68-72 wiper/washer motors that I have seen. Most have washer motor on top, connected to a canister, which I believe is part of the washer motor.

The one that I have just appears to be the wiper portion, but not quite. It does not have the attached canister and it does have a different shape than a standard wiper motor.

Could this be an aftermarket wiper/washer or did chevy change the wiper/washer motor config sometime in 72?

Since the washer portion does not work anyway, I pulled an original from the junkyard. I hooked it up and noticed that the switch appears backwards. Stop is high, low is low, and high is off.

Could my switch be installed upside down? The washer portion of the switch activates on the physical low and the physical high. It cannot be pressed in the physical off position.

Sorry for the length of the post and thanks for reading this far!

Let me clarify.

The switch that I am concerned about is the interior slide switch. When I connect the new (junkyard) motor to the car, and the interior slide switch is in the off position, the wiper motor is running on high.

On your 72, can you invoke the washer when your windshield wipers are running on high?


Thanks,

Tom.

The ground runs to the switch?

I was lazy, and did not replace the original motor assy. I just used the connectors to connect the junkyard one and used the body of the motor as the ground.

I'll bet this invalidates all the testing that I have done?


Thanks,

Tom.
