Where is my steering column grounded. My horn does not work when ignition switch is on

If the horn sounds at all, to me, that means the horn relay is ok. The horn relay is in the underhood fuse box.
What you might try is a redundant ground wire from upper steering column support bracket to known good chassis ground.
I saw a service bulletin relating to horn ground on your vehicle, between steering column and chassis. if that is the problem, they have an improved steering column assembly, but, see if the jumper wire will work, first.

Is there a problem with horn wiring in the steering column? The safest fix is to fix so the horn button on the steering will work. I'm not sure I understand your problem?

You could mount a separate horn button on the dash, but, that isn't the safest thing to do because your used to the horn button on the steering wheel.

If you mount a separate horn button, all you need is the horn ground that goes up the steering column, it is black. Find the harness under dash that goes into your steering column, black wire, just to test, use jumper wire from that wire to good ground, if the horn starts sounding, that's it. Run that wire to horn button. Also, you may need to run second ground from that horn button, if it doesn't ground through mounting bracket.

the first you can do is to check fuse! secondly is to check relay if theres no clicking sound ofcourse the power source from the battery, battery ground, body ground, ignition switch, horn switch, steering column switch, these are all the posible cause of not functioning.

Probably your horn cam in column, this can be checked and diagnoist easily, I believe it is a dark green wire that comes down the steering col. wire harness. If you grd. this wire horn should blow, how it works is when you push on the horn pad it grounds the circuit to relay and relay switches and puts power to horn to blow.Also make sure your steering column is grounded, which is usually through the rag joint to steering shaft

Hello, Dan. First, disconnect the negative (-)/ground on the battery Dan are you mechanically inclined. If not then don't attempted this job.

You will need to remove all the plastic covers on the steering column. Remove the horn ring.--two screws under the steering wheel. Remove the horn ring and disconnect the horn plug. Remove the steering wheel nut. Use a steering wheel puller to remove the steering wheel.

Remove the turn signal switch that fit around the upper part of the steering column. Then remove the some of the parts that are associated with the steering wheel and/or column.

Now, look at the ignition switch flange, it a big chunk of aluminum. Now look for a large aluminum dowel pin 5/8" in diameter that is driven into the chuck of aluminum but it is parallel to the steering column.

This aluminum dowel pin will have to be drill out before you can get ignition housing off, If there is adjustable steering column lever, remove this also.

Now, once the dowel pin has been removed, looking for a **** in the ignition housing. Take chisel and insert into this ****, drive the chisel into the **** until the ignition housing is loose to be remove by sliding it up over the steering column.

If you buy a new ignition switch, on purchase the switch with keys. Don't buy the hole new ignition housing.. If you do it will get expensive.

In the ignition (old) housing drive out the ignition switch pins that keeps the ignition switch in the housing. Install the new ignition switch re-insert the ignition switch hold pins.

I am fairly sure that Carquest/ NAPA some other larger auto parts will have ignition housing bolt. If they try to sell you a replacement aluminum dowel pin don't buy it. It is almost impossible to install the aluminum dowel pin without the proper tools, so use a bolt to squeeze ignition housing together.

Before putting everything back together. Now, check the new ignition switch to make sure it works. I wish you lot of luck. GB...stewbison

The horn has power all of the time but does not go off untill it is grounded. The switch in the steering wheel is the ground when you press it completing the circuit and sounding the horn. The alarm does not use the steering column or steering wheel ground path to "beep" the horn, it uses its own ground. The problem then will more than likely be in the steering column, steering wheel switches, or clock-spring. The clock spring is not for the clock. It is a spiral-wound wire set that allows the steering wheel to turn and not bind up the wires going into the steering wheel. It is called a clock-spring due to the "spiral" wound design of the connector. The horn ground wire in the steering wheel gets its connection through this clock-spring, so it may the source of your problem. It would require some electrical diagnostics to verify the actual point of failure.

You missed something putting the column back together. IDK the design of the wheel, but if all the wires to the column are good, I'd look at the switch itself in the column. Probably not making contact.

Ignition Switch Removal & Installation To Remove:

1. Disconnect battery negative cable.
2. Disarm air bag system.
3. Remove driver air bag module.
4. Loosen screw and lift horn pad to remove.
5. Remove lock nut and washer. CAUTION
   Do not hammer on steering wheel. Damage can occur to the energy absorbing portion of the steering column.
   
6. Pull dynamic damper forward and lift up to remove.
7. Remove steering wheel.
8. Remove steering column shrouds.
9. Remove lower cover.
10. Remove multifunction switch.
11. Remove entire lower portion of dash.
12. Remove mounting fasteners and lower steering column.
13. Remove bolts and separate ignition switch from steering column.

To Install:

1. Install ignition switch to steering column and install bolts.
2. Raise steering column and install mounting fasteners.
3. Install lower portion of dash.
4. Install multifunction switch.
5. Install lower cover.
6. Install steering column shrouds.
7. Install steering wheel.
8. Install dynamic damper.
9. Install washer and lock nut.
10. Lift horn pad and install screw.
11. Install driver air bag module.
12. Connect battery negative cable.

A fuse always blows for a reason. The reason your fuse must have blown was because of a short to ground in the horn switch. That means the power side of the horn switch is currently touching ground or metal or that the switch is bad on the inside. The more remote possiblity is that you have a short somewhere in the wiring harness. It is always typical for a component to go bad before a harness.

Here are some notes directly from chrysler, let me know if you need any clarification:

Testing and Inspection Notes WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS AND SEAT BELTS/AIRBAGS BEFORE ATTEMPTING STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

1. Disconnect and isolate the battery negative cable. Remove the lower steering column cover/knee blocker. Check for continuity between the metal steering column jacket and a good ground. There should be continuity If OK, go to Step 2. If not OK, refer to Steering and Suspension/Steering Column and check for proper installation of the steering column mounting nuts.
2. Remove the driver's airbag module. Unplug the horn switch wire connector. Remove the horn relay from the Power Distribution Center (PDC) . Check for continuity between the steering column half of the horn switch feed wire connector and a good ground. There should be no continuity If OK, go to Step 3. If not OK, repair the short circuit as required.
3. Check for continuity between the steering column half of the horn switch feed wire connector and the horn relay control circuit cavity for the horn relay in the PDC. There should be continuity If OK, go to Step 4. If not OK, repair the open circuit as required.
4. Check for continuity between the horn switch feed wire and the horn switch ground wire on the airbag module. There should be no continuity If OK, go to Step 5. If not OK, replace the faulty horn switch.
5. Depress the center of the airbag module cover and check for continuity between the horn switch feed wire and the horn switch ground wire on the airbag module. There should be continuity If not OK, replace the faulty horn switch.

you must check the contact switch on the steer wheel.
