How to remove the Ducato Steering wheel to repair intermittent horn function.
I'm posting this to help members on a subject I've hunted for to fix the horn on my motorhome, which would only work when the steering pointed in certain direction, not really much good. Anyway procedure for removal is as follows for steering wheels WITHOUT an airbag only.

PROCEDURE
1. Make sure you set the steering wheel direction pointing straight ahead prior to removal.

2. Prise and pull off the horn push from the steering wheel and remove electrical contact wire from the spade connector at rear of horn push.

3. This is the hard part, how to remove the plastic retaining shroud from the steering wheel. The shroud is held in place by 4 off plastic retaining clips, 2 at top and 2 at bottom. Using a small thin bladed screwdriver inserted through the holes adjacent to the retaining clip and prise up to release, do this one at a time until all 4 are free, you can then pull the plastic shroud free.

4. Remove electrical wire from spade connector at rear of plastic shroud.

5.Use a 24mm socket and extension bar to remove centre retaining nut. BEWARE make sure steering wheel is in correct position prior to removing.

6. Remove steering wheel.

7.If you are needing to fix the horn or the indicator cancelling the following is for you.

8.Clean the brass rotating boss at rear of steering wheel. (This will be covered in grease from wheel and be the cause of your problem.

9. Clean and reposition (pull up) the 2 brass contractors in the steering column boss.

10. Position indicator cancelling device ring so that the steel pin is at 6 o'clock, the pin will locate into the hole at 6 o'clock in the steering wheel.

11. Replace wheel and refit parts in reverse order.

Best of luck
