So when the combi switch goes do both low beams go out or can just one go out?

 

both went out on mine before I did the fix listed earlier. It's a pretty simple thing to do. As stated though make sure you disconnect the battery so the airbag doesn't deploy. Make sure you have you radio code (if stock radio).

 

I've changed that thing 3 times already and it just broke on me again :@ stupid piece of c#$%. No wonder they changed them to the dial afterwards.
