The Volvo lost dash illumination, as well as HVAC illumination today. I think I can say with 99% certainty that the issue is a faulty rheostat dimmer switch, which I can find on ebay cheap, and replace in minutes.

See?! EASY.

Why do I get the feeling I’m going to be intimately familiar with all of the minor issues that 850's can experience? I say “minor issues” because that’s about the level which I feel like I can take care of on my own, not because I don’t think I’ll run into bigger problems.
