Hi all, I am a new member with an odd problem on my CLK, quite simply I have warm air coming out drivers side only when turning on the air con. I have read many issues but non on the CLK as quite a few Mercedes member mention the duo valve issues but I am quite sure the W209 does not have these valves so I really am stumped so I am turning to you guys in the hope someone recognises this problem on my CLK. Thanks in advance for any help or advise given.
