ALP 15 Passenger compartment ventilation noises
NOTESOnly deal with this customer complaint after a full check with the diagnostic tool
(fault reading and configuration checks).
The aim of the following operations is to check and, if necessary, eliminate any foreign bodies
(leaves, insects, other, etc.) in:
–the passenger compartment air inlet,
–the cabin filter housing,
–the housing and on the fan assembly.
Check the passenger compartment air inlet and the cabin filter housing:
Remove:
–the scuttle panel grille (see MR 371 Bodywork, 55A, Exterior equipment, Scuttle panel grille: Removal -
Refitting),
–the air filter access panel,
–the scuttle panel partition,
–the cabin filter.
Check that there are no foreign bodies (leaves, insects, other, etc.) and, if necessary, clean the passenger
compartment air inlet and the cabin filter housing.
Refit:
–the cabin filter,
–the scuttle panel partition,
–the air filter access panel,
the scuttle panel grille (see MR 371 Bodywork, 55A, Exterior equipment, Scuttle panel grille: Removal -
Refitting).
Check the housing and the fan assembly:
Remove the fan assembly (see MR 370 Mechanical, 61A, Heating, Fan assembly: Removal - Refitting).
Check that there are no foreign bodies (leaves, insects, other, etc.) and, if necessary, clean the fan assembly
housing.
Check that there are no foreign bodies (leaves, insects, other, etc.) and, if necessary, clean the fan assembly.
