My ac cycles on and off when it idles. Is the fan supposed to be running wehn I turn on the ac? The fan comes after engine the engine has been running for a while. AC doesn't cycle then. After fan shuts off the ac starts cycling on and off again. Could this be a switch problem? If so how do I fix. Note: Air is cold and all switches on dash working properly. Tajnks for your help>

Hi:
Low freon pressure can cause the system to cycle. Also, the fan should be on when the AC is running. Start with having the system's pressure tested.
