Wiper Motor on '80 245 200 1980

It could be the stalk switch or it could be the motor itself. When you switch from normal to high speed, it switches power from one brush to a second brush in the motor.

Frankly, the easiest test is to borrow a known good switch and sub it. You don't even have to screw it down -- simply plug the harness to it. This diagnostic should take only a few moments.

If you go shopping at the boneyard for a switch, remember that you need one for a 245.

Regarding the rear wiper, did you include a ground wire along with the new harness?

Probe around in the tailgate with a test light or voltmeter and confirm that the motor has 12 volts at it when the key is on and that a second tab has 12 volts present when the wiper switch is turned on.
