Also, in addition to my dash gauge lights suddenly not working and the AC Panel lights staying on, the right rear tail light has stopped working. I already have the upgraded circuit boards, have checked the bulbs, and checked the contacts on to the board. Also, the front right marker light is out, but I assume that this is just a bulb issue, but have yet to investigate. Any suggestions? Nick VIN 3092 PS: Previously, the A/C panel lights most definitely turned off when the headlights were turned on. The did not just dim.
