Hi all, I recently brought a 2000 Commo Series 2 Berlina. One thing with the car that is worrying me is when i turn on the 'circulated-air' button on the climate control, in 10 - 20 mins the climate control seems to just switch it back off by itself. Is this normal, or has it developed a mind of its own? (By the way, it switches itself off even when i dont have a temperature set/air con on.) Any thoughts are muchly welcome!
