02 - CLK320 Climate control
Hoping someone can ID button for me. Ordered a used climate control from a 2001 CLK320 which crosses to same as 2002 mine is PN# A140 830 2685. There is a button next to recirc button with the 2 arrows on one I received that is not on mine. Good news is I have AC, bad news no LED lights. Because of this different button I realize wiring has to be marginally different hoping someone can tell me what this button is supposed to do? Rather than fuss with LED issue I will be replacing with A140 830 2685 so really just a curious question. Thanks in advance. Unfortunately when I received I was in MA and car was in FL so I did nor realize difference until return period ended
