My '72 Coupe is blowing the fuse for the courtesy lights. I've removed and taped off the door switches, put in a fresh fuse and as soon as I close a door the fuse blows or if I let the lights on with the doors open it will blow the fuse after 15 minutes or so. I'm wondering if anyone else has had a similar problem with the courtesy lights. I can turn them on and off at the switch without any problem
My vette's giving me fits and the Buckeyes....well I can always work on the vette Saturday afternoons.

I have not seen this happen. But, the door jamb switches just supply a ground. So if they don't make contact, the lights just don't work. And due to the fact they ground normally, they won't blow a fuse.
So this indicates a problem with the interior light module. Take a look there, and see if there is any signs of damage or overheating, burned contacts etc.

Some times its tough to remember that most of the contacts in a Vette,dont put power to things,they only supply the ground,the power is already there
happens with me all the time

Thanks for the heads up on the lights. Electrical things always confuse me, but I will take a closer look at the lights themselves and their wiring.
