Hooter and volume controll failing on steering wheel

If you have airbags your spirel on your steering can be broken. It has a roled up flex pc inside that let the current flow from the hooter cover to the steering colum. On the older models they used a hooter pin that get worn and needs replacement.

Does the air bag light come on as well ? The clock spring in the upper steering column is use so your steering wheel button's have power an you can still turn the wheel from right to left . They break no an then ! How to replace clock spring in 2006 Hyundai Sonata

You should check the cabling, from the steering wheel, where you can press the hooter, till the hooter. I think one of the cables is blank. But if your not technical enough please visit a technician. Perhaps other cables are lose or bad too.

Hi
Sounds like the earth disc under the steering wheel but dont damage the s/wheel when removing and make sure its straight before removing and the same when refitting.

it could be fuse or a broken earth wire of the back of the horn

Go to www.vaglinks.com. You can download "Golf,Jetta_MKII_serviceManual.pdf". It has got all the d=info you need.

The alarm is connected directly to the hooter, but the steering has a neutral (earth) which is switched when you depress the pad. You must remove the pad and check the system,either it has a like ring/disk with a carbon brush or micro switches. but all that does is earth the neg side of the hooter.Maybe the wire is off somewhere between the hooter and the harness where it goes into the firewall.

first test for power at the horn using a test light if no power then its not the horn check the fuse if fuse is good your problem can only be the clock spring which is located underneath the steering wheel,remove the wheel and its right there replace it and you will have horn power again.

It all depends on the tools you have and if you have patience....this is the task for removing and replacing the switch:

Removal & Installataion
CAUTION These models covered are equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS and refer to the precautions in the Chassis Electrical Section.

1. Make sure the steering wheel is in the center position (wheels in the straight ahead position)
   
2. Remove the key from the ignition.
   
3. Disconnect the negative battery cable first, then the positive cable.
   
4. Wait 10-20 minutes for the back-up power to discharge. Do NOT proceed until the back-up power is discharged from the SRS system!
   
5. Remove the driver’s side air bag module and steering wheel, as outlined under the Steering Wheel Removal & Installation procedure in this section.
   
6. Remove the steering column nacelle, as follows:
   
   • Open the fascia lower access panel.
     
   • Remove 3 screws securing steering column nacelle halves together.
     
   • Release clips securing nacelle together and remove from steering column.

Remove the rotary coupler, as follows:

• Release rotary coupler connector from bracket and disconnect from harness.
  
• Disconnect rotary coupler connector from harness.
  
• Remove rotary coupler.

1. Release passive coil from steering column lock and lower the coil without disconnecting the harness.
   
2. Release front wiper delay connector from column switch mounting bracket and disconnect from harness.
   
3. Disconnect harness connector from wiper switch.
   
4. Remove 2 screws securing switch, carefully raise edge of switch bracket to clear location peg and remove switch.
   

Release front wiper delay connector (3) from column switch mounting bracket and disconnect from harness. Disconnect the wiper switch connector (4), then remove the switch mounting screws (5)

To install:

1. Install the new switch to bracket and secure with screws.
   
2. Connect harness connector to switch.
   
3. Connect front wiper delay connector and Install the connector to switch bracket.
   
4. Install the passive coil to column lock.
   
5. Install the rotary coupler, as follows:
   
   • Install the rotary coupler to steering column and connect connector to harness.
     
   • Connect rotary coupler connector to harness and secure to bracket.
     
6. Install the steering column nacelle, as follows:
   
   • Position the nacelle to steering column and secure with clips and screws.
     
   • Close fascia lower access panel.
     
7. Install the steering wheel and driver’s air bag module, as outlined in this section.

jj, here's the procedure:
turn ignition key to locked position and turn steering wheel to the left until the wheel is locked. Remove key.
While vehicle still on ground disconnect the steering column shaft coupler from the steering gear intermediate coupler. Remove the cotter key the nut and the pinch bolt.
Loosen wheel lug, raise vehicle support securely w/ jack stands, remove the wheels.
Raise the insulating wrap on the power steering return hose to expose the hose clamp. Remove the hose clamp and detach the hose, Drain ps fluid thru the hose.
Remove both tie rod ends from steering knuckles.
Remove the 2 bolts and loosen the 3rd attaching the anti-lock brakes Hydraulic control Unit (HCU) to the suspension cradle.
then rotate the HCU rearward to allow access to the cradle bolt and nut just forward of the hcu.
Remove the nuts and bolts attaching the cradle plate to the bottom of the front suspension cradle, then remove cradle plate from cradle.
Remove bracket attaching power steering fluid line to the front suspension cradle.
Detach ps.fluid pressure and return lines from the ps gear.
Remove the 3 bolts and nuts mounting the steering gear to the front suspension cradle.
Lower the steering gear from the suspension cradle enough to allow access to the intermediate coupler roll pin. Install a roll pin remover/installer tool (they always get u with that darn special tool, don't they?) or equivalent set up. Pull the roll pin out of the intermediate coupler. Separate the intermediate coupler from the shaft of the steering gear Remove the steering gear assembly from the suspension cradle. Well, it's too late to give the install procedure, but u seem to have it under control, so let me know if u need more info and how u make out! Merry Christmas!
