Cruise Control The cruise control system is engaged by the cruise "ON/OFF" main switch located on right of steering wheel column. The system has the capability to cruise, coast, accelerate and resume speed.
Removal 1. If the compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off. 2. Disconnect the negative cable from the battery. 3. Recover the refrigerant with a recovery/charging station.
Inspection 1. Ignition "OFF". 2. Disconnect the intake actuator connector. 3. Verify that the actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding terminal 7. 4. Verify that the intake actuator operates to the fresh position when connecting in the reverse.
