The dash lights on my 67 GTX haven't worked since I got the car last fall and the previous owner had no idea why they didn't work. I put it in storage for the winter right after I got it so I haven't pursued finding out what is wrong with them until now. I checked the fuse and it is good. The dome light works as do all of the exterior lights. Everything else electrical works as well. Besides the fuse, what else should I look for that may be the cause of this?
