Fitting Sun Visors With Illuminated Mirrors
Unfortunately for all but a few coupe's the Astra G is denied the luxury of illuminated sun visor mirrors. The astra coupe ones are only available for the passenger side and are notoriously difficult to find second hand. This guide will show you how to retro fit a set from a Vectra B.
First thing you need quite obviously is a set of Vectra B mirrors.
First we need to remove the old visors, these are a torx head screw. If you undo the screw and then put it back in by a couple of threads and use the torx driver to push the screw back into the fixing slightly this will help to push out the collapsed fixing on the back. The fixings need to be pulled out from the screw end as the other end of the fixing is held in place with a hook.
Once removed the collapsed clip will need to be reformed by pinching in the sides so that the top comes up.
will need to remove the Astra fixing from your original mirrors to be used with
your new ones, this is done by carefully cutting away the arrowed collar
(picture shows it partially cut away).
collar has been removed the fixing will slide off the shaft of the visor, retain
this fixing for assembly of your new visors.
the Vectra visors again the fixings need to be removed however this time we need
to make sure the visor and shaft is left undamaged, to do this bend out the 4
tabs on the Vectra mount like the one arrowed has been.
fitting the Astra clip to the Vectra mirrors make sure the part where the screw
fits is bent back into shape as this makes re-fitting of the visors much easier.
order to get the Vectra visor to fit in the Astra mount you may need to use a
craft knife to shave off the ridge at the point indicated by the arrows.
Vectra visor should then clip straight into the Astra mounting, the plug will
need to be removed from the end of the cable but as the astra will need new
wiring fitting anyway this will not cause a problem.
fitting the visors the cables will need to be extended, i used some twin core
flex as it makes feeding the cables through easier and provides an extra layer
of insulation. i chose to solder the connections as space is somewhat restricted
in the headlining behind the mounting.
joints were then heat shrink sleeved to insulate and keep out moisture.
were then PVC tape wrapped over the join to provide mechanical strength for the
somewhat delicate wires of the visor.
routing and joining in the wires we need to remove the interior light, this can
be carefully pulled out by hand. the wires from the visors will need to come out
through the hole behind the light marked a, this is tricky to say the least and
i found it easier to use a spare piece of cable and feed it though from this
hole to either side and then tape the visors wire to it so that they can be
pulled back through to this hole. point b is where i have fitted an earth point
for both the map lights on my interior light and now the visors, luckily
Vauxhall put a hole there so all was needed was a stubby self taper.
the wires threaded through to the hole in the middle the visor can be fitted
into place by first locating the bottom hook in place and then pushing the top
of the clip back.
from visor coming out through hole behind light.
you find getting the clips back in difficult try putting the screw in by a
couple of threads and then pushing the clip into place using the torx driver,
once in place tighten the screw to secure it.
out your new visor to see if it opens and closes correctly, i found mine had a
habit of popping out of the clip when shut.
seemed to be because of how close the clip was to the edge of the visor and it
was catching on the covering, the way i found of solving this was to trim a very
small amount from the edge of the plastic covering as arrowed below.
visors now need to be wired in, strip back the outer insulation by a few inches
to allow the grounds to be run separate from the lives.
the grounds are connected to a ring connector and grounded using the earth point
behind the interior light.
lives are again using a crimp connector joined to the permanent live on the
wiring can then be tucked into the headlining and the interior light replaced.
back and admire your work.
