Steering wheel not centered

I would test the clock spring. Common failure point

bingo , first ever post with such a good test (ding ding !)
the steering clock spring contacts are bad.

that is the problem. (issues are pet stains)
now cure is new clock spring assembly.
how to fix it is covered in the service manual
Generic:

1. disable air bags SRS.
2. pull off bag from center of steering wheel.
3. pull off steering wheel. spec tools. *(called puller)
4. remove clock spring and replace it.
5. reverse order to finish up.

no Renault's in USA so no books to share here. 2013 zero.
last one here 1987 , long long gone and forgotten.

You will need to disconnect the steering shaft from the rack on the engine side of the firewall, make sure the wheels are pointed straight ahead to make it easier for replacement. You will need to disable the air bag system and make sure the column is locked before taking anything loose, too many revolutions of the steering wheel will ruin the clock spring. Take the lower trim off from under the dash and unbolt the column. Remove any electrical connectors and the shift linkage and shifter/ brake interlock. That should about do it.

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.

Follow correct procedure. You must do so, or you could trigger the air bag. First, take off the negative battery terminal. Wait 15 minutes for the residual charge to disappear-there is a back-up power supply. Point the wheels straight ahead, steering wheel centered, and turn the key to the lock position.
Two bolts hold the airbag module, hidden under small covers on each side of the wheel. Unscrew the bolts and lift off the module, and disconnect the module's electrical connectors. Also any other electrical connectors for wheel removal. When handling the module carry with trim side pointed away from you. Set the module down in a safe place with the trim side facing up.
Remove wheel retaining bolt and pull the wheel off. If stuck, use a 2 jaw puller to remove. Careful not to damage the screw threads on the steering shaft. If no marks exist on the wheel and steering shaft, you must mark it for placing the wheel back on the same position. Now you can work on the switch. Warning: with wheel removed, do NOT turn the steering shaft, or the clock spring will not be centered. This will make the air bag inoperative when you have it back together. If the clock spring must be removed, post back- there is a procedure for centering the clock spring, also for its removal. The reason to have the ignition key in lock is to prevent the steering shaft from turning.

whith the engine running and the vehicle parked bush on the steering wheel to activate the horn while rotating the steering wheel at the same time. If the horn beeps at certain points in the steering wheels rotation than either the clock spring has gone bad or the horn contact button has gone bad in the multi-function switch.

The only way to remove a clock spring assembly is to remove the steering wheel. Of course, if your vehicle has an airbag system (SRS) you'll need to unscrew it from the back and disconnect that first. If you don't have a steering wheel puller, you're going to need one, as this will make the job a LOT easier! You'll be able to borrow one from a "Loan a Tool" program such as at Auto Zone or Advance Auto Parts. Next, make a "timing mark" on the shaft and the inside of the steering wheel so that it's assembled and centered the same as when you removed it. Start with the steering wheel in the centered position when you make your timing mark for better ease of the operation. Once the steering wheel is removed, disconnection and replacement of the clock spring assembly is pretty self-explanatory. Just look for the attaching screws, remove them, and disconnect it from the harness. Use the new clock spring assembly as a good reference point.

I hope this helps! :)

try to look for a fuse.

The "clock spring" is a slang term used to describe the round electrical contact below the steering wheel inside the steering column, that transfers the switch contacts in the steering wheel to the actual vehicle. Your problem is more than likely the bearing in the top half of the steering column. Disconnect the battery and remove the air bag and steering wheel nut, steering wheel, and electrical switches, then look at the mechanical bearings or bushings at the steering shaft and case unit, the problem should be visible at this point. Hope this helps, let me know.

The part is still available from GM. It is part # 94857236.

You must be careful when replacing the clock spring as it controls the SRS system.
You will need to remove the steering wheel airbag and and the steering wheel itself.

Important: Perform this procedure in order to prevent deployment of the air bags from the reserve energy supply power.

1. Remove the CIG and IGN Fuses from the junction block (1), which is located near the base of the steering column.
2. Remove the lower steering column trim cover.
3. Turn the steering wheel so that the vehicle's wheels are pointing straight ahead.
4. Remove the key from the ignition switch
5. Release the inflatable restraint steering wheel module coil connector locking mechanism.
6. Disconnect the inflatable restraint steering wheel module coil connector C3
   
7. Remove the Instrument Panel (IP) compartment (2)
   
8. Release then unlock the IP module connector (1).
9. Disconnect the IP module pigtail.
10. Release and unlock the driver and passenger seat module connectors.
11. Disconnect the driver and passenger seat modules.
