ac control on 1996 Dodge Ram 2500

My truck's ac controls aren't working. The air comes out of the defrost and floor instead out of the dash. My cruise control is also not working. I was wondering if there was a connection. Thanks Keith

Often times these systems both can run on vacuum supply from the engine. Check the vacuum hoses, especially near the firewall, if the supply vacuum hose is broken, you can lose both these systems.
