ALP 2 Air distribution fault
NOTESOnly refer to this customer complaint after a complete check with the diagnostic tool
(no faults should be present or stored, especially fault DF012 Distribution motor circuit).
Special notes:
Adjusting the air distribution or ventilation controls switches off automatic climate
control mode.
Note:
The air distribution motor is located on the RH side of the distribution - ventilation unit,
above the footwell air duct.
Check that the air circuit (cabin filter, scuttle panel grille, air ducts and ventilation grilles, etc.) is not blocked.
Repair, clean or change the cabin filter if necessary.
Also check that there is no air flow fault: see ALP 3 Air flow fault.
Ensure that the blower unit is properly sealed. Also check that the air distribution ducts (right-hand and left-hand,
upper and lower) are correctly connected to the housing as well as the refrigeration pipe in the glove box (if the
customer complains about a feeling of cold air on the passenger's side).
Repair if necessary.
Switch the passenger compartment fan to maximum speed,
the temperature control to maximum hot or maximum cold,
and move the air distribution control.
Check that the air outlet is the one selected.
Note:
For information about the air flows according to user selection,
see the air distribution table shown in the interpretation of
parameter PR011 Distribution flap position.
Has the customer complaint been confirmed?
YES
Remove the distribution motor and check the condition of the
flap control (star-shaped mechanism).
Is the flap control damaged?
NO
NOThe air distribution is operating
correctly.
If necessary, explain how the
system works to the customer
again.
AFTER REPAIRPerform a complete check using the diagnostic tool.

ALP 3 Air flow fault
NOTESOnly consult this customer complaint after a complete check using the diagnostic
tool.
Check that the customer knows how to work the air conditioning system properly.
Is the passenger compartment fan working?
YES
Check that the air circuit (cabin filter, scuttle panel grille, air ducts and ventilation grilles, etc.) is not blocked.
Ensure that the blower blades are in good condition.
Repair, clean or change the cabin filter if necessary.
With the cabin filter removed, put your
hand into the housing to ensure that the
evaporator is not obstructed and that
there is no ice.
Is the evaporator obstructed?
NO
Ensure that the blower unit is properly sealed. Also check that the air distribution ducts (right-hand and left-hand,
upper and lower) are correctly connected to the housing as well as the refrigeration pipe in the glove box (if the
customer complains about a feeling of cold air on the passenger's side).
Repair if necessary.
Check that the air recirculation flap does not remain closed when in the recirculation position. On the diagnostic
tool, status ET062 "Recirculation flap position" should display OPEN (the flap can be seen by removing the
windscreen frame).
Repair if necessary (apply the fault finding procedure for fault DF021 Recirculation motor circuit).
Does the fault disappear when the air distribution is
changed?
NO
NO
YES
YESRepair, see ALP 5
Remove the evaporator and clean if it is obstructed.
If there is ice on the evaporator, carry out a conformity
check of the temperature sensors (internal, external
and engine coolant temperatures). Depending on
vehicle equipment, check that the interior air
temperature sensor micro-turbine is working correctly
(if it is faulty it may cause the measurement to be
incorrect).
Replace any faulty components.
Ensure that all the air vents
are open.
If the fault is still present,
see ALP 2.
AFTER REPAIRPerform a complete check using the diagnostic tool.
