1964 Valiant "Get Runnin & Drivin"

Got it tagged today and title applied for. I test drove it but it started raining hard. Wipers came in and worked great then stopped. Came back on. Then stopped. Did this about five or six times so I took it back home. Slobbed RainX all over the windshield because it's GETTING DRIVEN to work tomorrow. Now I need to figure out the intermittent wiper thing. Yall got any ideas?
