Having a problem with wipers. Took a wiper motor from ´67 Belvedere which I believe to be 2-speed (red, blue and brown wire). Then I have a switch and think it might be 3-speed (7 wires) but I can only find "two klicks" from it. Wipers only work sometimes in left position, in middle and right position nothing happens. Mostly wipers dont work at all from the switch.

Could I have bad or wrong switch or even wrong motor for barracuda ? In wiring diagram there seems to be red, blue, brown and green wires going to wiper motor and wiring to switch is just like my barracuda has.
