		TEST RESULTS
1	ACTUATOR OPERATION CHECK	EVERYTHING OK	PROBLEMS ENCOUNTERED	OPERATION
	Connect the diagnosis equipment to check whether there are error codes consistent with a fault related to lack of actuator operation.	End of diagnosis	Faults related to actuator malfunction have been identified	Go to Step 2
2	ACTUATOR CONNECTIONS CHECK	EVERYTHING OK	PROBLEMS ENCOUNTERED	OPERATION
	Check whether the electrical wiring connections are loose. Detach/reattach the connection on the actuator side and on the control support side. Check whether the error is still present	End of diagnosis	The fault occurs again	Go to Step 3
3	ACTUATOR MOBILITY CHECK	EVERYTHING OK	PROBLEMS ENCOUNTERED	OPERATION
	Check the operation activating the function that the actuator should carry out manually. With the engine running, switch on the passenger compartment heater fan at maximum speed. Place the flaps in the various recirculation positions via the control/control unit (manually). Check the air flow in the passenger compartment by placing your hand on the vents.	End of diagnosis	The recirculation actuator is not working correctly	Go to Step 4
4	CHECK FOR THE PRESENCE OF BLOCKAGES ON THE RECIRCULATION ACTUATOR	EVERYTHING OK	PROBLEMS ENCOUNTERED	OPERATION
	Check whether there is a mechanical blockage/breakage of the flaps in the recirculation actuator	Go to Step 5	Presence of mechanical blockages on the recirculation actuator	Remove the mechanical blockages/Replace the actuator Op. 5040D75 AIR CONDITIONING RECIRCULATION FLAP CONTROL MOTOR - R.R
5	CHECK OPERATION OF THE CLIMATE CONTROL SYSTEM CONTROL UNIT	EVERYTHING OK	PROBLEMS ENCOUNTERED	OPERATION
	Check that the climate control system control unit is working correctly	End of diagnosis	The climate control system control unit is not working correctly	Replace the climate control unit Op. 5040D15 CONTROL UNIT WITH KNOBS AND BUTTONS FOR DUAL ZONE AIR CONDITIONER - R.R.
