2 Speed Wiper Motor Configuration

[Shane Kelley]

Working on my 71 RR and it has 2 speed wipers. Everything in the cowl was loose and laying in the bottom. This is the only 2 speed set up i have ever messed with. Every other car I have owned or built had 3 speed. Service manual is really vague the centric part of the linkage. I have tried a couple different ways. One way the wipers would stop all the way up but didn't seem right. They would do a couple strokes and every so often go all the way down in park position and then continue normal operation. Sometimes they won't shut off at all. Then I flipped the arm on the motor but then it made knocking noise and everything came loose. Any pics on how this thing should look assembled or nice diagram?

I've never done a 2 speed either, but maybe this helps a bit?

These thing are sensitive to bad grounds. Make sure the motor and switch are both grounded. Also check for the correct motor they are not all the same. Refer to this link also provided in the previous post

The motor you need is 69-71 C-body, 70-71 E-body and 71 B-body only. Contact me if you have other questions

Additionally testing of the motor outside the car is ideal as you can catch problems before you put it all together.
