74 C10 Wiper Switch
 

Wiper switch is a 2 speed with a push for washer pulse. Seems no difference between position 1 and position 2 speed. Is this in switch or motor?


TIA

The motor.

I agree. Although there is also the possibility of a bad connection in the wiring.

On the 1977 & older wiper motors, the switch grounds both the "low" and "high" terminals for low speed operation. It only grounds the "high" terminal for high speed operation.

So a bad connection between the switch & motor in the "low" speed circuit will result in the motor running at high speed on both switch settings.

Update....While working on temp gauge not working correctly in the last couple of weeks, wipers would not work, yet they did 2 days before. Checked connector on switch and found I knocked it off while checking temp gauge. Reconnected switch, now wipers work as they should. Have a 2 speed wiper and parks correctly. Strange how things work....or don't work.
Guess just a bad connection with switch connector.

Thanks to all the replies.
