Long story short, I left my window open. Lots of water got in, and now my switch control box (including fuel door release, etc.) doesn't work. Strangely, the green light that indicates when it's in auto headlight mode is still illuminated (but now sometimes extinguishes when I pull the e-brake). Is this a simple order another headlight control box from Volvo/Ebay or a much bigger problem? Thoughts?
