Now you can begin to remove the switch assemblies. Undo and remove the 4 small screws that hold switch assemblies inside the steering column and keep them safe with the 24mm nut from earlier.
Now it’s time to disconnect the electrical connectors from the switch assemblies. Around halfway down the steering column, the plastic shroud ends. Underneath this shroud is three electrical connectors. The two nearest the driver seat are the two plugs for the wiper and indicator switches. Give these a gentle tug to disconnect them and tuck them to one side, they can’t be mixed up so don’t worry.
With the electrical connectors removed, you can now begin to pull the switch assemblies up and out of the steering column. Do this slowly though as there are two pipes connected to the back of the wiper switch assembly for the windscreen washers. These can be disconnected at this stage and should have been depressurised earlier (see poic 4).
Now you should be able to remove the switch assemblies, but be careful not to break the plastic wiring sleeves as these tend to quite brittle with age.
With the assemblies removed, I could now see what had happened with my indictor lever, the bottom part of the lever mechanism that operates the switch had snapped ( see pic 5).
The indicator and wiper switch assemblies are joined to form one piece but are easily split.
They are held together with four metal sleeves and the two parts can be split easily using a screw driver (see pic 6).
Once they are split, you can replace either the indicator or wiper switch assembly (or both) and t the two back together using the four metal sleeves.
Once back in one piece, tment is the reverse of the removal. The hardest part of the tment for me was locating the wiring plugs under the plastic shrouding into the correct location to push the connectors home. This picture helped me to locate the plugs and they are shaped in such a way that they can be guided into position (see pic 7).
Once reconnected, I would recommend that you test all of the functions of the switches before re tting the screws and steering wheel, in case you have to take it all apart again!
Don’t forget that you have marked the steering wheel to line it up when you re t it too.
The last test should be the horn and don’t forget to re-pressurise the washer bottle!
