After pulling my dash to replace the heater core, I felt quite certain that all electrical connections made it back together as I followed a good write up on it and everything went fairly smooth(though time consuming).

Now that its all back together, I cannot for the life of me figure out why none of the instrument, dash, or center consol lights will work. I swapped in a spare dimmer switch that I know to be good, so I managed to rule that out. I'm terrible at troubleshooting electrical problems, anyone have any suggestions?

 

Try checking in your power distribution center under your hood. There's a little yellow mini fuse in there (20 amp if I'm not mistaken), that blows when messing around the dash.
