Fan Blower Rotor Blocked







Fault symptom
- The ventilation fan is not working.
- No A/C function.

On-board diagnosis

Type of diagnosis:
- Continuous

Enable criteria:
- Ventilation fan activated.
- Vehicle speed under 30 km/h.

Fault criteria:
- Fan motor is stuck or short-circuit to ground in fan motor circuit.

System reaction to a fault:
- The PWM output to the ventilation fan control is turned off. The output is reactivated after 3 minutes
- A/C function switched off.

Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.

Diagnostic help
- The fault code can be generated if there is moisture inside the fan housing or if the fan rotor is frozen.
