Place the passenger compartment
fan on full,
temperature control on
maximum heat or maximum cold,
and move the air distribution control.
Check that the air output
corresponds to the selection.
Is it correct?
The air distribution is correct.
If necessary, explain how the system works to
the customer again.
Check visually or by touch, on the right-hand
side of the air distribution unit,
that moving the control
moves the sprockets
and the lever.
Do they move?
Check the connection of the cable
to the air distribution unit
and the control panel
and check the condition of the cable and its
retainer. Is it correct?Change the control cable
or repair the connection of the cable (clip)
or change the faulty part
(control panel or distribution unit).
If the fault persists,
remove the air distribution unit and
check the distribution flaps.
Repair or change the assembly.
In the case of a ventilation problem,
check the ventilation ducts
and the vents.
Repair if necessary.
Check the adjustment of the air distribution
flap control cable.

is not blocked.
Repair if necessary.

Advise the customer how to use the heating
system correctly
(eg. : Do not place the passenger
compartment fan on full when starting from
cold, turn it up gradually instead).
Carry out a road test to observe the customer
complaints.
Is the test satisfactory?

Non regulated air conditioning.
Visually check that
the action of the control moves
the mixing flap.
Does the flap move?
Visually check
whether the flap travel is complete.
Is it complete?
Check the cooling circuit
(correct filling and bleeding),
the condition of the circuit (pipes,
connections, conformity
of the circuit...).
Repair if necessary.
Does the fault persist?
Readjust the control cable
(cable which controls the sprockets to the
right of the air distribution unit).

With the engine cold, remove the engine
coolant thermostat and check that it is not
jammed in the open position.
Is it correct?
Check that there is no unwanted intake of
cold air into the passenger compartment
(seals, grommets, cables ...).
Repair if necessary
Does the fault persist?
Check the air inlets (particle filter)
and outlets.
Partially blocked air inlets or outlets
reduce the flow of heated air
into the
passenger compartment.
Repair if necessary.

circuit.
NOTE: if the coolant level is too low, the cir-
cuit may become unprimed when driving at
low load and at idle.
Repair if necessary.

Visually check that moving the control
moves the mixing flap.
Does it move?
yes
Check the coolant circuit.
NOTE: fitting an oil, water or air cooler which
has not been approved by the research centre
and which is incorrectly connected may re-
duce or even stop the flow of coolant in the
heater radiator.
Repair the coolant circuit if necessary.
Does the fault persist?
Remove the heater radiator.
Clean or change it if necessary.
Check that the components which were removed are connected correctly.
