A 1992 Buick Roadmaster with 5.7 liter V-8 A/C has full charge and cools perfectly while parked or idling. When driving the system will cut out and change from "auto" to "auto-econ" and no longer cool. When returned to idle the system can be restarted. While in park engine idle can be increased over 2000 rpm and system remains operable. What switch would cause this to occur?
