a
aDrain the refrigerant circuit using a refrigerant
charging station (see 62A, Air conditioning, Re-
frigerant circuit: Draining - Filling, page 62A-8) .
aDisconnect the battery (see ) (80A, Battery).
aRemove:
-the wiper arms (see Windscreen wiper arm: Re-
moval - Refitting) (85A, Wiping - Washing),
-the scuttle panel grille (see Scuttle panel grille:
Removal - Refitting) (56A, Exterior equipment),
-the scoop under the scuttle panel grille (see Scoop
under the scuttle panel grille: Removal - Refit-
ting) (56A, Exterior equipment).
aRemove:
-the air filter unit (see Air filter unit: Removal - Re-
fitting) (12A, Fuel mixture),
-the upstream oxygen sensor (see Oxygen sen-
sors: Removal - Refitting) (17B, Petrol injection). Equipment requiredrefrigerant charging station

IMPORTANT
To avoid all risk of damage to the systems, apply
the safety and cleanliness instructions and opera-
tion recommendations before carrying out any
repair:
- (see 62A, Air conditioning, Air conditioning:
Precautions for the repair, page 62A-1) ,
- (see Vehicle: Precautions for the repair) (01D,
Mechanical introduction).
Note:
Use blanking plugs for the fuel circuits with part
numbers 77 01 208 229 or 77 01 476 857 to plug
any openings exposed to the open air. They must
be clean. Do not use any which have already been
used to plug a fuel circuit.
WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which are
open to the air.
WARNING
In order to avoid any refrigerant leaks, do not dam-
age (deform, twist, etc.) the pipe.
WARNING
To prevent the surrounding components from over-
heating, do not damage (tear, pierce, bend, etc.) a
heat shield.
Any damaged heat shields must be replaced.WARNING
Consult the device's operating manual to avoid
incorrect use.

CLEANING
I - CLEANING PREPARATION OPERATION
aRemove the cabin filter (see 61A, Heating, Cabin
filter: Removal - Refitting, page 61A-6) .
II - OPERATION FOR CLEANING PART
CONCERNED
aRemove any foreign matter (leaves, insects, etc.)
from the cabin filter housing.
a
Apply AIR CONDITIONING CLEANER using an ex-
tension piece. The end of the extension piece must
be positioned at the base of the evaporator.
aSpray the entire contents of the can.
aLeave the product to work for 15 minutes.
aRun the fan assembly very slowly for 5 minutes.
III - FINAL OPERATION.
aRefit the cabin filter (see 61A, Heating, Cabin filter:
Removal - Refitting, page 61A-6) . Note:
For the part number for the air conditioning
cleaner (see Vehicle: Parts and consumables
for the repair) (MR 411, 04B, Consumables -
Products).
WARNING
Do not spray the cleaner via the air inlet, as this
could damage the fan assembly.
