no horn, bad fuse, confused

[fivespeedsteed]

so my horn didnt work once when i went to hit it. either button. and i looked at some fuses and a 20 was broken in the middle. i pulled it out and went to put the spare in, when it touched it started sparking and lit the fuse up blue. now that ones bad. can i use a bigger one to stop it from doing that? does anyone have a fuse diagram? what goes to what and whats the proper way to change them? thanks.

Never install a larger fuse to try and fix a problem. You will only create bigger ones (ie. a fire). Obviously, there is a shorted to ground somewhere in that circuit.

horn, cig lighter and clock is what is on that circuit. may be others, but this is on a 86. should be the same for yours.

Make sure there is not a coin or something in the cig lighter. Even a shorted lighter element.

Make sure there is not a coin or something in the cig lighter.

This is the usual culprit.

The horns typically develop an internal short to ground, which causes the fues to blow.

The horns are located under the car on the driver's side, forward of the front wheel well. Disconnect BOTH horns, replace the fuse: if the fuse blows immediately, the problem is most likely in the cigar lighter circuit. If not, then press the horn button on the steering wheel: if the fuse blows the problem is in the wiring between the horn relay and the horn. If doesn't blow when you press the horn button, connect ONE of the horns and try again. If it still doesn't blow the fuse, connect the other horn. Chances are that the first horn you re-connect will blow the fuse. Whatever horn blows the fuse at this point has an internal short and is trash. Time for a trip to the junkyard...

on that 20 amp fuse?

jrichker thanks for that im gonna try that. i think im right but any 20 amp fuse should be the same right..

 

[fivespeedsteed]

becasue my cig lighter sucks too. my clock on my radio is always right though..

 

[jerryD]

well that is what my haynes says. i would unhook the cig lighter under the console just to eliminate that from the equation. but the horn trick that jrichker posted, sounds like more of cause for your fuse to keep blowing.

it is deffenitly a short somewhere,horn or cig lighter...and yes any 20 amp fuse will work

I just had that same fuse blow, I noticed the cigarette lighter stopped working, then the horn after being cut off. A quick glance at the owner's manual shows a list of the fuses by amps and the corresponding slot they go in, also the functions affected by each.

In this case the slot is 16, the fuse amperage is 20, and the horn, cigarette lighter, and cruise control are affected.

so the best way to keep the fuse from blowing is to put it in with the horns disconnected? it is a short then? how do i fix that?

had that problems once... got it out with a pair of needle nose. Once i got that out, put in a new fuse, my horn still doesnt work.

so i looked in my cig lighter hole and there was a dime. took it out disconnected horns, drove to advance auto got 5 20 amp fuses, put on in the fuse pannel one in the spare tray, and pluged up one horn, worked, pluged the other in, back to normal. i had no idea change could come out of my ashtray and fall in there so i put my cig lighter back in. thanks guys what would i do without you.

Didn't want to start a new thread so I'll piggyback here. I'm have the same type of issues, no cruise, no horn, fuse blows, etc. My console is removed right now so no cig lighter even plugged in. I removed both horn wires from the horns themselves and the fuse didn't blow when I put it in. I hooked up the horn closest to you when you are looking from the bottom and still no blown fuse. I take the jumper wire and hook it to the top horn and the fuse blows. I'm guessing it's a bad horn then?
