Help with wiper motor & switch

Hi,

Going through my new 68 Barracuda and my wipers don't work. Sometimes the go up and stop, if I bang the motor they might go a bit more. But, thinking I need a new motor. I can't pass inspection without working wipers.....

My question is, do I even have the right setup in place? Below are pics on my motor and switch. I can't tell if that is a 3 speed motor, but the switch is definitely a 2 speed and it looks fairly new along with the wiring.

Could that be causing my issue? Or and I doomed to dole out a ton of cash for a new motor?

Or do I have other options without having to rewire everything?
