How do you remove horn switch on proton persona?

Answer 1

If the horn is not operating the fault will almost certainly be the ribbon cable in the steering wheel. It is located under the air bag, and is not repariable. The purpose of this cable is to coil tighter and looser as the s/wheel is turned. Proton call it a "clockwork spring" cost £77 from proton. there are four points of contact to operate the horn. They are unbreakable. To gain access to the ribbon cable, remove the rear s/wheel covers. Then from rear of wheel remove two torque screws holding the airbag and horn switch assembly onto the frame of the s/wheel. You will need a 30 mm torque screwdriver. On the right hand side of the s/wheel at the rear, is a detachable plastic plate, 300 by 500 mm. Tease it out with a small screwdriver. Look through the resultant hole and you can see one torque screw. I found it necessary to kneel outside the vehicle, drivers side, and to shine a light through the hole. not at all easy to see. On the left side of the steering wheel at the rear, is a circular rubber bung, about 100 mm diameter. Again tease it out. You will have to undue the left torque screw through that small hole, I did it more by feel. Once both screws have been removed it will then be necessary to unclip two fasteners which also hold the airbag and s/wheel ribbon cable assembly in place. Very hard to see them, they are located near the screws you have just removed. I found it necessary to bend the clips in the open position using a small screwdriver. When you have now removed the screws and undone the clips, lift the horn and airbag assembly off the lower s/wheel frame. Carefully remove the airbag and horn plugs. Next remove the s/wheel. Important, mark the position of it before removing. I did this by placing a broom on the dashboard and resting on the drivers seat. I then stuck tape on the seat, s/wheel and dashboard to mark the alignment of the s/wheel with wheels dead staright ahead.

Once you have removed the s/wheel you can now see the ribbon cable assembly. Its a sealed unit, not repairable (it actaully says so on its label) Unplug the horn and airbag connections. Two important points. The horn only works with ignition switched on. When fitting the replacement "clockwork spring" ensure you wheels are pointing dead ahead. Refitting is the reverse of the procedure. The best of luck !

To remove the horn switch on a Proton Persona, first locate the screws or clips securing the switch cover in place. Once those are removed, carefully detach the cover and access the horn switch components. Disconnect the wiring harness and unscrew the switch from its mounting. Replace or repair the switch as needed and reassemble the components in reverse order.
