The dash display lights do not work suddenly. I am trying to figure out which fuse is linked with those. I thought it was the headlights so I changed those fuses...No dice. The headlights work but the interior ones do not.

Thanks!

2nd one down on the right IIRC.

Thanks. I just changed that one out. It's so hard to tell if the lights work now because of the daylight. Even cupping my hand around the clock doesn't tell me much.....Hope that solved it.

If I remember right, your dome light is also on that same fuse.

Looks like it didn't work. Great.

Check your running lights. I believe they are on the same fuse, too, at least from what I can tell from a cursory look at the 78 wiring diagram. If your running lights are good, but your dash lights are out, you need to check the rheostat for the dash lights. A quick test is to unplug the rheostat and jumper the black wire to the red wire with blue stripe. If your dash lights come on, it's your rheostat. I have no idea about whether or not the rheostat can be cleaned or repaired.

Thanks guys. I just took her for a spin and the lights now seem to work. Guess it was really bright today. Those stock display lights are kinda dim .

Be sure your fuse contacts are clean. Your combo switch may be dirty, too. Dave, aka Zs-ondabrain, will take apart and clean your combo switch (and turn signal switch). He's got plenty of experience and a good reputation for it, too. Look for Caig Deoxit at Radio Shack. Lots of people swear by it for cleaning electrical contacts.

As for the dash lights, dim lights are a common complaint. Search on this site for plenty of threads about replacing the bulbs or taking off the green covers.
