bad ground to horn
bad relAY TO HORn
bad wires to all horn circuits
bad horn button.
bad clockspring contacts in steering hub.

no matter way we use a voltmeter to solve this, riddle in 5min work.

i always start in the middle (training) to make 1/2 the possible go byebye in 1 simple test.
if the relay dont pull in at failure, bingo. 1/2 problem solved.
is this clear?
that would say the relay is bad, or power to it lost
or the horn button path is dead.
causing 2 more simple tests.
ask. if you own a $10 meter... volt meter. of any kind ever made.

SOURCE: My 2003 Suburban is stuck in 4 wheel low

It sounds as if it is a module eprom issue. When the key was turned on the program was scrambled.Try disconnecting the negative and positive battery cables. Once both are disconnected from the battery, touch the two cables together for 1 minute, this will drain the reserve energy in the module. This process will reset the modules to factory default.
Reconnect the battery, positive first then the negative.

SOURCE: Chevrolet Suburban 4 Wheel Drive Indicator Lights

Just serviced my own 4x4 Suburban, by buying a 2nd hand encoder motor and replaced the old one, which was trashed by the winter salt. The device is prone to failure since it's made of alluminium and water has an easy time of entering the unit and trashing it.

CAUTION: Abbreviated gratuitous information of how an encoder motor was serviced. If unqualified to deal with repair, seek professional service.
CAUTION: Read at one's own risk.

To replace it, you need to crawl under the vehicle and remove the front drive shaft;

Disconnect the electric harness to the encoder motor, followed by unbolting it.

Take replacement encoder motor and install. There may be an issue with aligning the cogged cam of the transfer case to the encoder motor. If so, the vehicle's 4 wheels will need to be raised off the ground. The engine started, transmission in Park, and using a Vice-Grip® wrench gently rotate cam clockwise approximately 1/16 to 1/8 of an inch, then while set in this position, stop engine. Now attempt to align and attach the encoder motor.

After successfully attaching new encoder motor, attach its wiring loom.
Test vehicle.

I have a 2003 cavalier;and the horn doesn;t work . ineed help taken the steering wheel off to check wireing

Before i took the steering wheel off i would locate the horn itself and unplug it and run a straight wire from each battery post and touch one wire to each contacter on the horn to make sure the horns not bad itself. But to take the steering wheel off you have to unbolt the airbag from the back remove it and then you should be able to check the horn contacter without pulling the steering wheel.

Rx7 horn problem, connected directly 2 battery it works but when i push the horn i dosent and i cant locate the horn relay or fuse..

Did u check both fuse panel one under the hood the other in the cab under or on the side of the dash. Also sometimes the switch inside the stearing wheel will short or just stop working due to dust or excessive force. If the car has a drivers air bag it will be costly to replac this switch due to the explosives used in the air bag deployment system. good luck and good hunting

2003 Mitsubishi Lancer horn not honking

Usually when the horn doesn't honk it's a blown fuse

try running the ODB sensor on it... it should tell you the code...

then you can look the code up and it should tell you the problems...

Usually AutoZone or Advanced Discount Auto will do this for free for you :)

Horn nor control on stearing wheel work

Its likely the clock spring, aka sliding contact. Fords/Lincolns are famous for these failing. It's basically the component behind the steering wheel that provides power to everything on the wheel, while allowing the wheel to spin. $160 for the part.

Can i fix my suburban horn myself?

First check and make sure your fuse is the correct size this could be your problem, if the "horn" is one of the two in front that is a simple fix and I'm sure you could do it, get the replacement unbolt the old one and bolt in the new one, if it the horn buton on your stearing wheel that will cost a little more but its another simple fix, check with the chevy dealer for the parts.

Horn And turn signals

try moving the tilt wheel feature up and down to see if the condition worsens or improves. There's a ribbon cable on the outside of that column that may have worn off the insulation in some spots. If that's it, you'll need a steering wheel puller to get to it. You may not have to replace the cable, just insulate it from inside the column. You can use tape, but a wide piece of heat shrink, cut along one side would be cleaner.
