Interior Lights No Workie

[Tentsontop]

Finally got around to pulling the dash apart to replace the D light, install CDL switch, replace other burned out bulbs, and found the reason my rear heater wasn't working was the switch was disconnected. While doing the 7 pin mod I cleaned up the ground for the dome lights, but still no go. Everything interior wise works except the visor vanity lights and the dome lights. I've checked everything (fuses/ground) and everything seems fine. No juice getting to the domes. I've yet to pull the headliner to investigate further. At this point I'm wondering what else can I possibly check. Any ideas?

You probably did this but is the bulb good or did you use a test light to see if there is juice?

The bulbs are fine. I used a voltmeter to see if it had juice, but no enchilada. I've looked at the wiring diagram and can't think of anything else to try. I really thought it was a bad ground but that doesn't seem to be it. Pulling the headliner seems like the next logical thing to do to see if something's corroded or shorting out up there. Not looking forward to that. I know I could pull it, but I'm not sure I could get it back up like it was.
