Howdy , My W220 driver side power window question here are :
From Master windows switch connect to Power seats control switch : I had only driver side window went down only on AUTO mode not manual mode but NOT UP at either mode .the rest of all other three are working normal. I had tried to manually reset this but no luck .
Finally I replace it with newer power window switch unit and got the same result , now it was an interesting happen when I decided to open this switch to inspect the switch's circuit board and find out is driver side window only can operates when I hold both UP & DOWN button at the same time then window will does it job both way but reality was I can't do this when it is a completed assembly .
Question to whom may has same experiences like this : Possibility faulty from Power seat control switch despite it still function normal ? Where else can I look into it ?
Replace another Power seat control switch ? ( Pretty expensive for even used item)
