Just wondering if anyone knows an easy fix. All the other electronics work, except my cluster lights dont turn on. I tried using the dimmer switch for the first time and it didn’t really work, it just went out, so I have a feeling its the switch. Is there a fuse for the gauge cluster?

There should be a fuse that could be blown, there is a fusebox on the driverside cabin, just on the kick panel to the left of the clutch. Check the sticker in there for the right fuse, if it’s not there check the fusebox inside the engine bay. That’s about all I can think about, I have a sneaking suspicion that it might be the TCU unit that’s burned out like on so many 240’s.
