Early A Variable Speed Wiper Motor & Switch

I am wondering if my variable speed setup is the reason we can't get an intermittment regulator to work as we have in other cars. If it were possible to convert to a 2 speed setup, maybe that would be the fix. At least with the results i get, the variable speed wasn't all that different
Hello,

What do you mean that it was not that different?

Which regulator is intermittent?
