    Question Very Strange Electrical Issues 93 STS

    Hi, I have a 93 Cadillac Seville STS that is having some strange electrical issues and am looking for some help, please! At night, my interior dash lights will not work unless my foot is on the brake pedal, and even then they are very dim. Also, when I turn the left turn signal on, the dash lights blink at the same rate as the turn signal. I have also noticed that all of the left side body lights are out...taillight, front marker light etc. I pulled the "left parking light" fuse in the trunk and it was blown so I replaced it. Then everything worked ok. I turned on the turn signal once more to check it and ALL the lights except the headlights started blinking. I turned the car on and the fuse blew once more, so now I am back where I started from, no left lights and having to push on the barke pedal to get any interior lights at all. Please help!! THanks!

    Why don't you post this in the Electrical or Seville forums instead of the engine/transmission forum. You'll get better answers there.

    Good luck...

    It sounds like maybe a wire shorted somewhere and melted the individual wires that control that stuff together before the fuse blew. Maybe at a block connector or something. Are all the other fuses that control that stuff OK?

    have you ever had the radio out? There is a harness that runs through the lower dash that is related to the cluster lights. Possible?

    It looks like it has intermittent short somewhere in turn light cuircuts. Plus, bad grounds of stop lights, that is why you got other lights on when you press brake.

    Thank you all so much for your help, OldGamer is right, it was a rear tail light causing the issue, apparently on of the bulbs fused with the connector in the circuit causing it short. all is well now after replacing wiring connector and fuse. Thanks!!
