So the other night I'm fiddling with the 83' working on the electrical system. I hooked the heater blower back up and I lost all my interior lights including dash. The fuses are all fine, and he dome light works in the ON position just not as door. Is there some other hidden fuse I could have blow lol? HELP, My little blue light to light up my speedometer is getting old fast.

 

I'd look for a ground problem.
