Hi mbraz. I have not had reason to to work on this system as yet. But from what I
have picked up if you have the Electronic Climate Control System, then the first
thing to try is a reset.
To do this, I believe, you press the 'Auto' and 'Off' buttons, at the same time, for
several seconds with the ignition turned on.
You must check the vac pipes and electrical cables at the Recirculation Air Valve
Solenoid. On left hand drive cars you must remove the lower trim panel on the
drivers side of the fascia panel for access. You will then find it on the left hand side
of the Air Distribution Unit.
You must also check the Recirculation Air Vacuum Unit. This is mounted on the left
hand side of the Blower Motor. On our right hand drive cars, to access this you would
remove the glove box. I don't know what you would remove on Left Hand drive cars.
You really need someone who has done these jobs to advise you further. So if anyone
on here has, then now is the time for them to add their thoughts.
Sorry I can't be of any further help.
