Where is the fuse for the horn,blinkers, cruise control and lighter

Question edited for clarity, 'fuse', unless you light it 'fuze'.Question moved to sub category.

If the radio has an inline fuse, it will be within 82 of the plug at the rear. They are built into the harness. Unlikely because there are three fuses covering audio.

Fuse #19 (15 amp) controls the cruise control. It also powers the horn so check your horn. If it works then check the cruise controls ground. If the fuse is good BUT the horn still doesn't work, then check the horn relay, as it also powers the cruise control. Check all wires/connections going to these parts also.

there is two sets of fuses on this car i think. The centre console lights are on fuses inside the car under the dash, is your interior light not working either?

These are just ideas, but In my simple attempt....start with checking, or have someone check every fuse in the fuse box. Another thought is that the turn signal indicator arm that controls blinkers, high beams has finally gave out. And when it did, it might have shorted out the horn. Being a 1993, it has probably seen some usage. Does the cigarette lighter work?? Also check the fuse in the fuse box that controls the horn, because in some of my experiences, the cigarette lighter and the horn are sometimes on the same fuse.

jnjkingbird, It sounds like this problem is the clock spring as I don't believe that the horn and the cruise control would share a fuse. However, they do share a circuit in the clock-spring. You can check for power at each unit (horn and the cruise control) which would confirm this. Check each fuse as well. Good luck with this.

Could be a fuse or two that blew out. Check fuse box and pull out fuses and inspect starting with the cig lighter fuse, horn fuse, cruise ctrl, and anything labeled as such.

Check the fuse for your cigar lighter/horn. I've seen the fuse blown from the lighter shorting. It will caue the cruie not to work also. I hope this helps. Good luck.

yes usually your horn and Cruis control share hte same fuse and circute along with cig lighter

MMM most have solenoid on the curcuit ..i usually see them connected on one side through a clockspring on the closed side of the relay
