Question about 2001 Jeep Grand Cherokee

4 Answers

Horn malfunction My horn had a few episodes of going off continuously without warning until I tapped the switch a few times and it turned off. Then it sounded and didn't shut off. In a pinch, I pulled the fuse to turn it off and am driving it without a horn. My mechanic tells me the least expensive fix will be $800 for a whole new used assembly. Is there a way to safely disassemble this area (involves the airbag area) and investigate the switch diaphragm and see if there is a way to repair it? Anyone had experience with this?

This is a simple fix all you have to do is unhook the battery for atleast thirty(30) minutes to disarm the airbag Then remove the airbag by removing the allen screws in the rear of steering wheel you will see the wires going to the horn and you can see if the wires are touching under the air bag. The horn worrks off of ground so the wires is rubbing some metal somewhere under the airbag

Isuggest that instead of using usual horn system you can try (AH ).NOWADAYS THESE Automotive horns are installed in almost all automobiles, trucks and other automotive vehicles. Automotive horns are intended for use as a warning device to provide warning to other drivers, bicyclists, pedestrians, bystanders, or animals of potential dangerous conditions in the vicinity of the automobile. For example, the horn may be used to warn pedestrians or persons in the path or vicinity of a moving vehicle of the presence or location of the vehicle.
In recent years, it has become increasingly apparent that automotive horns are commonly abused by drivers to show or vent frustration, or to express anger at actions by other drivers or bystanders that are perceived as discourteous. The abuse of the automotive horn by impatient or angry drivers is a common nuisance. Abuse of the automotive horn in this manner may be particularly prevalent in congested traffic conditions, such as in cities or heavily populated suburban areas where traffic is heavy. Nevertheless, abuse of automotive horns has become so common that it is of concern in a wide range of urban, suburban, or rural settings, for example in shopping malls, parking lots, and in the vicinity of sports arenas or recreation centers.
The abuse of automotive horns also raises a number of public safety issues. Abuse of automotive horns is associated with the increasing problem of "road rage," a condition caused by driver frustration. Under these circumstances, the abuse of the automotive horn may provoke a violent response by a nearby driver.
The abuse of automotive horns in the manner herein described is characterized by a length and repetition of horn use that is unnecessary when the horn is properly used, leads to annoyance to other drivers and non-drivers, and also increases the general level of "noise pollution

Can you switch your horn relay switch with you cooling fan relay switch because i think my cooling fan relay is burnt out, i can go without a horn until i buy a new relay for the fan


If it looks the same, it is. Go ahead and switch them, but try the horn after you do it. If the horn still works, the relay is not your problem.

Horn problem on 2001 ford explorer xlt


Hi there,

Inspect the following components, in this order (with key off) until you get it working:

** Disconnect the plugs from the Horn terminals. Run separate jumper wires from the Batt (NEG & POS), to the horn. If horn does not work, then replace horn. If horn works fine, then continue....

** Check fuse # 10 (15A), in the Battery Junction Box - replace if defective. Check horn operation.

** Check Horn Relay (also in the Battery Junction Box) - remove the relay, give it a gentle tap, and plug back in. Check horn operation.

If all the above prove ok, then the fault lies in your steering wheel/horn switch assembly.

1995 Volvo Horn keeps blowing with key in ingnition, and engine running


You can do this for now so its not driving you crazy, then get it fixed.
If your car horn starts blaring and seems to be "stuck" (it won't stop blowing), you could be in for a few embarrassing moments. There's nothing quite like the stares and expressive hand gestures you can draw as your horn takes on a life of its own. There are a couple of things you can do to get the horn to stop.
If it got stuck when you pressed on the horn switch on the steering wheel, it could be because the switch itself is stuck. Press the horn switch again, or tap it a few times to see if it gets unstuck.
Turn off the engine and look for your fuse box. Look through the circuit descriptions and see if you can find one for the horn. If you can, pull the fuse. This should silence the horn immediately.
If you can't find the fuse box, can't remove the fuse, or the horn doesn't turn off, then you need to resort to more drastic measures. Open the hood of the car and try to locate the horn. If the rear of the horn is visible, you might be able to see the wires that lead to it. Disconnect the wires. If you can't disconnect them, then cut one of the wires. If you cut the wire, wrap the resulting two ends of the wire with tape so that they can't short out your electrical system.
You could disconnect the main wires that run to your battery. You shouldn't cut these but should disconnect them using a wrench. This might "reset" the horn. Hook the wires back up and if the horn doesn't turn back on, you should go directly to an auto repair shop to figure out what is going on. If the horn does turn back on, you'll need to locate and disconnect (or cut) the wires to the horn as previously described. Then, go to the auto repair shop and let them replace the horn for you.

In the cluster of relays under the hood(passenger side ) of a 1988 300zx, which one is the horn relay?


this is a tough one, there are a few relays there you will need to have someone push on the horn and you feel relays until you feel a clicking on the relay and that will be the one, alsom check the fuse first to make sure thats good, most of the time its a fuse or bad horns a horn relay doesnt go bad to often so start first with the fuses, heres a diagram of the insidee fusebox, the horn fuse is # 9 and holds a 10amp fuse, hope this is helpful.johnjohn2_45.gif

How do you troubleshoot a defective horn 2001 ford crown victoria?


Find the horn and use a test light to try to ground out one of the two terminals to see if it sounds. If it does, then the horn is ok, but it may be the switch in the steering wheel.

To test the steering wheel switch, take the horn cover off of the steering wheel and search for the lead for the button and try to ground it out. It may sound if you do this. If it does, then there is something wrong with the button connection at the clock spring.
---
Here are instructions on how to remove and replace the steering wheel which can help to understand how to troubleshoot the horn switch which is related to the clock spring electrical connector:

Steering Wheel Removal & Installation To Remove:
NOTE: Make sure the wheels are in the straight-ahead position. Disconnect the battery ground cable and wait at least one minute.
WARNING
To avoid the risk of serious personal injury, read and follow all warnings, notes and instructions in the deactivation procedure. Deactivate the supplemental restraint system (SRS).
  1. Remove the driver side air bag.
  2. Disconnect the clockspring electrical connector.
  3. Remove and discard the steering wheel bolt.
  4. Use steering wheel puller and remove steering wheel.
CAUTION
Removing the steering wheel without using a puller can damage the column bearings. Using a suitable puller, remove the steering wheel.
Remove the steering wheel while routing the wires from the clockspring through the steering wheel.
WARNING
To avoid the risk of serious personal injury, read and follow all warnings, notes and instructions in the reactivation procedure. Reactivate the supplemental restraint system (SRS).
To Install:
  1. Install steering wheel, while guiding wires from clockspring through.
  2. Install new steering wheel bolt. Tighten to 30 ft. lbs. (40 Nm).
  3. Connect the clockspring electrical connector.
  4. Install the driver's side air bag.

HORN DID NOT WORK SO WENT AND GOT A FUZE PUT IT IN NOW THE HORN STAYS ON WHY IS THAT?


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.

Jeep Grand Cherokee Horn Switch Malfunction.


I have the same problem.  I pulled the fuse out, in the box under the hood, on the passenger side of the engine, by the coolant overflow.  It killed my horn issue.
Funny enough, the only part of my horn that I miss is the beep when locking my car.  I don't really use the horn and perhaps when some idiot cuts me off one day, I'll be sorry.
I just had my AC Rad fail, and fixed that today.  I am picking up my Jeep tomorrow, and have asked the mechanic if he has any ideas.

Hi,

As in most electrical problems, it would be required to do a bit of tracing/diagnosis to determine which is at fault. Most automotive horn system works on the same basic design. A switch in the steering wheel that energizes the horn relay that in turn powers the horn(s). A self activating horn could be caused by:
1: intermittent short in the steering wheel horn button;
2. intermittent shorting out horn relay;
3. intermittent short in the wiring.

Basing on the above possibilities, diagnostic/corrective action would involve:
a. tapping on the steering wheel (not the horn button) to see if jarring it would activate the horn, if yes then the problem is with the horn switch and often cleaning the inside/contact points of the switch should be corrective;
b. tapping the horn relay with the handle of a screwdriver to determine if jarring it would activate the horn, if yes then the problem is with the horn relay which of course would need replacement;
c. the wiring would be a bit more complicated if not time consuming. It would be necessary to wiggle the wires coming from the steering wheel/column to the main harness, to the fuse/relay bank finally to the horn to check at which point the trouble would resurface. Taping any exposed/bare/scraped wire would be corrective. It should be noted that the steering horn switch often would be "to ground" meaning the horn switch is switching the horn relay by providing the negative path, the relay is constantly supplied with B+12.

There are some instances that the horn could also activated by an alarm system.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
