WIPER SWITCH/WIPER MOTOR

My barracuda sat for years while ive been working on it so i can drive it this summer. The wipers always worked. Afew weeks ago i finaly got it out and took it to a local cruise in. On the way home i ran into some rain. The wipers decided they didnt want to work. Afew days later i was looking to see what was up & i turned them on & the wipers moved a few inches & stoped. Not sure whats up with them. Its a 3 speed wpier switch & 3 speed motor. Any way to test the motor & or switch ? After looking at some pictures im not sure now if mine is a 3 or 2 speed motor. This is my first 67 & the 3 & 2 speed motors look alot like. I will post some pics of the motor & switch
