I found out this evening my dimmer switch stopped working. The speedometer display and MFD are on full bright and I'm sure I've been able to turn them down before. I tried making the adjustment with the headlights on and off and it never mattered. I also recall seeing somewhere on the MFD that I could set it to full bright, but I never even saw that button on any of the screens. Perhaps because it's already detecting full current from the adjustment knob? The switch itself feels normal, has good feel and the detent for full bright is noticable. If I had a multimeter handy I could shoot the resistance through the variable resistor, but I don't, nor do I feel like popping it out of the dash. I guess I have to go back to the dealer now..... :angry: Any ideas?
