[Jim '57]

Hi, I believe I have a two speed W/S/W motor on my 57 Bel Air but can only get high speed when I rotate the wiper knob (& boden cable). Is there a way to adjust this better? Thanks. Butch

The knob controls a cable that slides the switch that is on the motor. I would start there. disconnect the cable and see if you can get both speeds by sliding the white piece .
Good luck,
Jim
