Hey guys, looking for some help. The El Camino's interior lights should come on when I pull the headlamps. The headlamps come on and work fine, but my interior lights do not. I found out the fuse was blown, so I replaced it. When I tried with a new fuse, it worked for about two seconds and then went out again. Tried it two more times and it did the same thing. It does have aftermarket gauges with lamps in them but im not sure they are the issue, it used to work perfectly. I would think there is probably a short somewhere, but I don't know. If it is a short, I don't know where to start. Any suggestions?
