That's why you need a 12 volt test light.

Clip end of test light needs to clip on a good ground, a metal part under dash and other end you touch both ends of the fuse and check which fuse only lights on one end. If power is going thru fuse it will on both ends, if filament inside fuse is blown no power will come out the other side of fuse. It is most IMPORTANT that the clip end of test light is attached to a good ground!

Exactly! Your test light should light up on both sides of the fuse or it is blown. Corvettes can be tough to find good grounds on because of the fiber glass body.

Thank you,

Well, they all work. I thought I found it as one did not test ok, but when I pulled it out my interior light on dash went out so I put it back.

I was told there is some sort of delay relay behind the glove box, could that be shorted out somehow?

Thank you.

Unfortunately my 1974 does not have a spare tire light so I can't be much more help to you. Hopefully someone with the light can be of some help to you.

Still no resolve?

All fuses are working / tested.

Anyone know anything about the: relay behind the glove box ?

Could that be blown out somehow by this? How could I get to it and test it.

Thank you.

The light under the rear is on the same circuit as the interior lights. There is a timer behind the glove box that's turns the lights off after a set time. If your interior lights work when you open the door and turn off after a while then that timer and that circuit is ok. The tire light should go on & off with the interior lights, if not then the bulb or the wires to that bulb are bad. Hope this helps.
