Indicator and Wiper Switch Assemblies Removal and Repair

The first step is to remove the steering wheel
from the steering column. Before you start,
it’s worth straitening the steering wheel/front
wheels so that when the steering wheel goes
back on, you know where to line it up.
The steering wheel is fitted to a splined shaft
within the column and is fixed with a single
24mm nut.
To access the nut, the horn push in the centre
of the steering wheel has to be removed. The
horn push is usually made of plastic and is often
brittle, so prizing off with a screw driver or metal
scraper is not the best idea. I found that using
a finger nail was sufficient, working my way
round the horn push and lifting upwards (see
pic 1).
With the horn push removed, the 24mm nut
should be revealed and there will also me a
lead and crimp connected to a spade terminal.
Remove this crimp to disconnect the lead and
move to one side to create some space for a
spanner.
Using a 24mm ring spanner or socket and
ratchet (an open ended spanner can slip easily),
loosen the nut but do not remove at this point
(see pic 2).
Mark the position of the wheel in relation to the
shaft using chalk, pencil or paint pen to assist in
lining the wheel back up on fitment.
Now, with the nut still fitted, give the steering
wheel a tug upwards to free it from the splined
shaft. It should become loose but the fitted nut
will prevent you from smashing your face with
the steering wheel (believe me!).
With the wheel loose, remove the 24mm nut and
lift the steering wheel off too. This will expose
the indicator and wiper switch assemblies fitted
to the top of the column (see pic 3).
At this point, you want to remove the cap from
your windscreen washer bottle to depressurise
it (otherwise you will create a drinking fountain
later on!) if you have pressure in your tank,
you’re the exception

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 fit the two back together using the four
metal sleeves.
Once back in one piece, fitment is the reverse
of the removal. The hardest part of the fitment
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 refitting 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 refit it too.
The last test should be the horn and don’t forget
to re-pressurise the washer bottle!
