Having a problem with my 2003 Dakota Quad cab 3.9. The"Air bag" light came on, when I pushed the Cruise control coast button the light would go off. So I replaced the "clockspring" with a new one from O'Riely auto parts. Now ONLY when it gets hot, above 90, the light comes on and stays on until the key is cycled. Code p1200. I'm having trouble finding diagnosis info. Any help would be greatly appreciated.
