82 model Have replaced the headlight switch and most bulbs. I think I have checked just about all fuses and they seem to be OK. I have turn signals, headlights, backup lights, BUT no park lights(back lights and front park lights and no dash lights. Is there something I'm missing such as an in line fuse. This is my first attempt at a makeover so I know I have lots to learn. Any thoughts or suggestions would be welcome. Thanks in advance.

The park lights get their feed(12v) from the light switch, on the brown wire. Check this wire for 12v at the light switch first(with the lights on).
(The parking lights also are run thru the turn signal switch. This keeps the front turn signals from coming on when you mash the brakes.)
The park lights are fed from the "Tail" fuse in the fuse box. Use a voltmeter to test the fuse with it in the box, and the light switch on. Don't trust just looking at it, and thinking the fuse is good. Testing with a volt meter will tell you how much voltage there is at the fuse. It's possible there is a break in the circuitry in the fusebox, that keeps the "Tail" fuse from getting a full 12v.
If the fuse tests good, check for 12v on the brown wire at the switch, with the lights on. If there is 12v there, you have a bad connection for the park light circuit. The most likely place for this is the firewall "pass-thru", where the wiring goes from the inside to the under hood area. Of course, this wouldn't explain why the tail lights don't work. That's why it sounds like there is no power on the brown wire at the switch.
The dash lights are also fed from the light switch, on a dark green wire, to the fuse box(Inst. Lts), and out on a grey wire to the printed circuit board behind the cluster.
It sounds like there may be an issue with the fuse box, or the light switch, even tho you have replaced the switch.

Excellent advice above.  And dead-on if someone hasn't messed with your car.  Mine is a 79 and I had a number of lighting problems - the big one being that the headlights would just cut out at times.  Finally got fed up when even putting in a new switch didn't work.  Turned out the previous owner had apparently pulled/broken the wire to the instruments - and connected them to the headlight wire (big yellow if I recall).  IN the process he had somehow created a short that burned the contacts in the headlamp dimmer switch - so i had multiple items to fix to get it right. 

If the above advice from Adam's Apple doesn't work - check your wiring diagram (available on another thread here) and trace each one to make sure there is  no re-wiring to fix!  Some folks have tied in radios or CBs (remember those?) and all kinds of other junk to the lights, as the Corvette fusebox had a limited number of accessory hookups.  Good luck.

The problem with my lights has been resolved. Went back and checked all fuses and as you suggested one looked OK but did not function. Thanks so much for the guidance guys. Just got back from giving the "ole girl" a spin around the block. Ain't it neat when people look and smile!!

Kewl!! Glad ya got if figured out!!

I had a ghost problem on my truck, bought it new so I obviously know the history. It got to where the lights would blow fuses when it rained. After much swearing and bulb checking, it's a dually with all the running lights, the prob turned out to be a small cut in a parking light wire courtesy of the factory! GRRRRR!
