Tail ligbt problem

[Velsko]

The tail lights and dash lights of my 75 vette have not worked since I got the car a couple of years ago. The headlights, blinkers, and brake lights do work. I have changed out the tail light fuse but the problem is still there. I have had my dash out and the switch has all of the correct connections running to it so I am not sure if that is the problem. Can any of you help me with this?

When I first got my vette I searched for weeks trying to find out why my tailights didn't work, I followed every wire in my haynes manual, and after all that I figured out it was a bad ground... I don't know if this is your problem but it is very easy to check... also in my fuse box some of the connections were slightly corroded which is commen in an older car... If you can get a wiring diagram in it is infinitly helpful

I would check the grounds too. Also, the light bulb(s) may not be getting good connection.

At worst case, get a test light and start check the wiring. (use the manual for help)
