I have just about had it with this car. One thing after another. Almost 18K stuck into and it still doesn't run right. Okay, problem number 134598. I am blowing my tail light fuse consistently. When this happens I have no tail lights, brake lights or interior lights. Sometimes I replace the fuse and it last for a week. Now it is blowing when I get down the block. I replaced some chrome on my trunk lid and when I closed the trunk, the lights went out. I looked at all the wires and they appear fine. At least the ones in the trunk. When I attempt to put a new fuse in with the lights on, I get sparks and the fuse blows. When I attempt to put the fuse in with the lights off, I get no spark. Didn't try it with brake pedal depressed. Any ideas? I would hate to replace the whole wiring harness and still have the problem. Car is a 65 chevelle.
