L041 PASSENGER COMPARTMENT HEATER FAN NOT WORKING (CERAMIC RESISTOR WITH THERMAL FUSE BLOWN)

		Test results
1	FAN WIRING CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Place a suitable ammeter clamp on the positive line of the fan wiring and measure fan uptake at max. speed with the engine running, and check that current uptake is below 20 A	Go to Step 2	Current uptake above 20 A	Fan replacement Op. 5040C30 AIR CONDITIONING FAN - R.R.
2	FAN POWER SUPPLY FUSES CONDITION CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Check the condition of the fan power supply fuses	Go to Step 3	Fuses damaged or not working correctly	Replace the faulty fuses (looking for the cause of the malfunction)
3	SWITCH OPERATION CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Check that the switch is working correctly	Go to Step 4	The switch is not working correctly	Replace the switch Op. 5040D65 FAN SWITCH - R.R.
4	CERAMIC RESISTOR CONDITION CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Check the condition of the ceramic resistor	Go to Step 5	Ceramic resistor not working correctly	Replace the ceramic resistor Op. 5040C44 FAN MOTOR ELECTRONIC VARIATOR - R+R
5	CURRENT UPTAKE FAULTS CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Check all the components in the vehicle's electrical system that may cause irregular/excessive current uptake, such as battery and alternator	End of diagnosis	Fault found on the component	Replace the component that causes the fault
