"Blowing" FusesFuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating which can result in damage to the conductors, and worse the possibility of a FIRE which could destroy the vehicle. When a fuse [and replacement fuses] repeatedly blow, is an indicator of an UNSAFE CONDITION in that circuit, usually a short. Do not install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would invite damage to the wiring and an electrical system fire. The proper "fix" is for a qualifiedtechnician, who knows what he/she's doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with a properly sized fuse].
It it either a blown fuse, defective horn, bad ground, or defective horn switch. Check the fuse, if it is blown, replace, if it is good, run a wire to the horn directly from the battery. If the horn blows, suspect a bad horn switch.
The fuse for the horn on a 2002 Camry is going to be either under the hood, or inside of the dash. The dash might need to be take one to find it.Ê
Then you have a short in the wiring, the horn button is defective, or the horn itself is defective.
There is a dead short in the horn pad, take off horn pad and look for two wires touching or a hot wire rubbing on something that is grounded. First, disconnect horns in bumper area then press the horn button then check fuse. If the fuse is still good, hook up horns and press horn again. If it blows fuse it is the horn itself.
It could be the horn relay, a defective fuse or a shorted wiring. Need to check the wiring first, then the fuse and lastly the horn relay.
The horn and parking lights may be on the same fuse, you need to look for a frayed wire or connector leading to your horn(s), it may be touching metal somewhere causing a short. The horn itself may also be the problem to check it disconnect the wire connector from the horn(s) and try it, if the fuse still blows keep looking for a wire touching metal.
The horn relay can be found in the fuse box under the hood. The 1990 Toyota Camry horn relay is found in slot 12 and is rated at 10 amps.
Check the fuse first. If the fuse is good apply 12 volts directly to the horn. If it blows then the horn button on the steering wheel or wiring is defective. If not, the horn itself is defective.
Check the fuse, and all connections to the horn. If you find nothing wrong, then apply 12 volts directly to the horn. If it blows the horn is good, and the horn switch may be bad. If it does not blow, visit your local salvage yard for a used horn. dont think the fuse in the fuse panel is the only one for the horn... in the relay center under the hood there is a horn fuse as well, that was where mine was blown. good luck
It seems that you have a short-circuit on your horn circuit. Check to see if the terminals of your horn are touching any part of the cars body. Also see if you can disconnect the horns, change the fuse again, if the fuse holds then replace the horn(s)
Dead short in the horn or the wire. Try unhooking the horn and see if it still blows the fuse. Stop pusjing the horn so much! :-) Actually there seems to be a short or a bad horn. Check for the horn relay as well it may be stuck or bad.
It should written on the back of little compartment which covers the fuse box (on the left from the stirring wheel).
