I have a 97 base; the illumination for the gauges doesn't work. LEDs work fine, so at least I know how fast I'm going at night, but would love for this to work. Fuses B1, B10, and E1 are good. Looking at some other similar threads it seems like the ignition switch replacement is sometimes offered as potentially causing this. My question, is it worth replacing this to see if that's the issue?
