I have a '99 blazer with 174K. The interior lights stopped working a few days ago. I replaced the fuse and they worked for a few minutes then the fuse blew again. I know from the research that I've done that I shouldn't replace the fuse again until the short is found. Any suggestions on finding the problem? I am a D.I.Y.'er who, until recently, had only ever changed the oil on my own, so I am definitely still learning! I recently changed the plugs, wires, cap, rotor, and PCV valve. The fuse blew a few days later. I'm Not sure if that's relevant, but I thought I should mention it. I know that diagnosing electrical issues can be tricky so any suggestions or assistance would be greatly appreciated. Thank you!
