I have a 92 124 230TE with semi-automatic AC.
The ventilation system seemes to be stuck in recyclemode causing the windows an the air in general to build up a lot of humidity. The airdryer funktion works, but I would like to know where I can find the valve that switches between freesh air and recycled air in order to fix it.
(the light in the recycleswitch turns on and off when I operate it but nothing happens)

Thanks Rune
