For climate control systems:
Using the diagnostic tool statuses and parameters screen (passenger compartment ventilation sub-function),
check that the recirculation flap is in the external air position: status ET062 Recirculation flap position should
display OPEN. If it is closed when the user does not want recirculation, use the fault finding procedure for fault:
DF021 Recirculation motor circuit.
For manual air conditioning systems:
check that the recirculation flap is in the external air position. If this is not operating correctly (impossible to change
the flap to the exterior air position), check the condition and routing of the recirculation flap control cable. Eliminate
any constraints on it: kinks, cable restricted by plastic clips, etc.
Replace it if necessary.
Check that there is no mechanical fault with the recirculation flap (flap jammed).
Carry out any necessary repairs.
Is the fault still present?
YES NO
Is the lower heater matrix pipe (coolant
inlet) hot?
NOTE: Pipe located on the left-hand
side of the heater-air conditioning unit,
near the engine bulkhead.NOCarry out a check on the
coolant circuit and ensure
that thermostatic valve
opens at the correct
temperature.
Replace the valve if
necessary.
YES
If the vehicle is fitted with passenger compartment heating resistors,
check that these are operating correctly (not switching on
unnecessarily) by referring to the fault finding procedure contained in
the UCH technical note.
End of fault finding procedure.
AFTER REPAIRPerform a complete check using the diagnostic tool.
