1977 corvette dash lights went out - Corvette Chevrolet Cars & Trucks

In the picture below the arrow points to the courtesy light fuse.

I suggest www.Willcox.com/Corvette . Great site.

the wires coming from the column are for your brakes and blinkers. check fuses, i mean pull them out and inspect. on older cars sometimes they need to be pulled out and put back in from rust. most of the fuse boxes back then were made with metal that will rust and make a bad connection. try that and get back to me. also check with test light on both sides of the fuses.

you bleed like you would the brake system. there is a bleeder screw on the slave cylinder that you bleed the system.

The fuse box on a 1977 corvette is located at the top of the kick panel on the drivers side. It is just below the dash on the outside wall..

Look at the head lite switch for a burned resistor.

The first thing , this system works on vacuum there are vacuum lines that run from intake to storage can or cans then to light switch inside car then back out to headlights,

i would first start by starting the car and listen for vacuum leaks, you may want to follow the vacuum line form the motor checking for splits or cracks in the lines, listen around can, this can sometimes rusts and leaks vacuum, this can or cans are intended to store vacuum and use it when needed, if they are leaking then the lights will work slow until there is enough vacuum to open them, this goes the same for a bad vacuum line and light switch, the light switch is a two part switch, one part supplies power to lights and the other part is vacuum to open lights.

you will need to listen for a vacuum leak inside the car at the switch, (headlight switch) .

Make sure all lines are good and have no leaks, you will need to make sure the hinges to lights are free and not binding up.

ARE THE FRONT AND REAR TURN SIGNAL INDICATOR BULBS ON STEADY AS WELL?

Headlight wiring is towards the bottom of the page.

Hope this helps, have fun wrenching on that vette.
