Hello from Henderson NV,
I hope I can find an issue that can be fixed. I have a 1992 corvette and recently my tail-light, marker and front running lights do not work. My brake, head light and blinkers are fine...all fuses are fine unless I am missing a location to another fuse box. I am new to this group an also to this C4 I have. Before I go to a shop maybe its something someone has dealt with. Thanks
In a 1992, the "other" fuse boxes don't involve the tail lights.
I would suggest you re-check the TAIL fuse. Rear column, 2nd row down. Use a meter on Ohms to check it for continuity, or substitute another fuse such as the STOP/HAZ (which is good because the brake lights work.)
If still no tail lights, but with a known good fuse installed in TAIL, turn light switch to PARK, use your VOM meter set on DC Volts to probe each little hole in the fuse with one probe and the other probe to a good ground like the lighter shell. There should be voltage on both sides of the fuse. If = NO voltage, the light switch is faulty or there is a bad connection to the fuse. Check that the "prongs" in the fuse box are touching each other with the fuse not installed. If there is a gap between the prongs, try to massage them together with a dental pick.
