ALP 2 Air distribution fault
NOTESCheck that the air circuit (cabin filter, scuttle panel grille, air ducts etc.) is not blocked.
Make sure that the air circuit (cabin filter, scuttle panel grille, air ducts etc.) is not blocked.
Ensure that the passenger compartment blower is in good condition.
Repair, clean or change the cabin filter if necessary.
Ensure that the passenger compartment blower unit is properly sealed.
Repair if necessary.
Set the passenger compartment blower to maximum
speed with maximum hot or maximum cold and
move the temperature control.
Check that the blown air matches the request.
Is the air distribution correct?
NO
Remove the glovebox and the centre console in
order to visually check whether moving the control
causes the distribution flaps to move.
Is there movement?
NO
YESThe air distribution is operating correctly.
Explain to the customer how the system
operates.
YESCheck that the distribution flaps are in
good condition, the footwell distribution
flap linkages are in position, and that there
is no mechanical obstruction. If necessary,

ALP 3 Air flow fault
NOTES
Is the passenger compartment blower working?
Check all of the speeds: Does the flow vary in
accordance with the position of the speed switch?
YES
Make sure that the air circuit (cabin filter, scuttle panel grille, air ducts etc.) is not blocked.
Ensure that the passenger compartment blower is in good condition.
Clean or replace the cabin filter.
With the cabim 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 passenger compartment 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.
Repair if necessary.
Does the fault disappear when the air distribution
is changed ?
NO
See ALP5.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
NORepair, see ALP 5.
YESRemove the evaporator and clean if it is
blocked.
If there is ice on the evaporator, perform a
conformity check on the temperature
sensors (exterior and coolant
temperatures).
Replace any faulty components.
YESEnsure that all the air vents are open.
If the fault is still present, refer to ALP 2.
