With the engine warm and the passenger
compartment ventilation operating, vary
the position of the mixing flap from the
maximum hot position to the maximum
cold position and check subjectively that
there is a difference in temperature.
Is a difference in temperature noted?
Check the cold loop by checking the condition of the pipes and ensuring that the air conditioning system does not
have any refrigerant leaks (see Technical Note 6001A, Air conditioning, 62A, Air conditioning, Air
conditioning: Check). Repair the faulty pipes or components.

Carry out a full check with the diagnostic tool.
Check the condition and routing of the mixing flap control
cable. Eliminate any constraints on it: kinks, cable restricted
by plastic clips, etc.
Replace the lead if necessary. Unclip the cable from the side
of the heating/air conditioning unit and check the stiffness of
movement of each component: control button and flap
control on the air distribution unit. Check that there is no
mechanical fault with the mixing flap (flap jammed inside the
unit, etc.). Carry out any necessary repairs.
Is the fault still present?
