Just got done tearing apart my dash to see whats causing the back lighting not to come on. I figured it was the dimmer switch but when i disconnected it the LCD screen for the mileage turned off, so i figured the dimmer switch was working correctly. Not really sure how to ohm it out, it was constantly reading the same no matter where at it was, but the LCD screen responds to the dimmer switch, but none of the dash back lights are working. All other lights work fine, interior, ign key light, warning lights. i thought maybe the lights on the actual dash were in series. I ohmed out each light and they are all fine. I have double checked fuses, the only one blown is the wiper fuse. Im at a loss here unless that dimmer switch is messed up some how. Anyone got any ideas?

Also this is in a 1993 FD3S
