Blowing tail light fuses...need help asap

you have a loose wire, its grounding out and blowing the fuse.

you have a bad socket or a wire is touching the chassis. Remove all the lights in the back and see if it still blows. If it doesnt then its in the front or in the instrument cluster.

ya wiring is quite a thing, not really sure how to really go about tracing a bad wire other than use a test light, try and find the wire with no power with the key on, and that wire would probally be your problem.

I found this wiring diagram for an '86, it should be the same for your car. If you can read it the brown wire (on an '86 anyway) is the power wire for the lights and the black wires are the grounds. Always check your grounds first, bad grounds are what most elec problems are, or start. I'd first look back in the tail light panel to see if the ground connections on the body are good and tight and wiggle the wires and stuff too. I dont remeber if there is a tail light harness connector back there, check it out too.

If not that then I'd look at all of the running light wires around the car to see if the brown wires are exposed and touching metal and the ground connections. Then look at the headlight switch harness to see if tis burnt, corrosion in all the bulb sockets, or anything that seems 'wrong'.

It might be wise to get a test light to help you, I got a test light from walmart that lights red for ground and green for power (or vice versa). A voltmeter is good too, but you can probably get away with a test light in this situation.


Oh, and the brake lights are on another circuit, so they'll work anyway.

e-brake???

auto panel light or the lights for the console or ash tray
