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.



You 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).


step 4

Once collar has been removed the fixing will slide off the shaft of the visor, retain this fixing for assembly of your new visors.


step 5

On 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.


step 6

Before 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.


step 7

In 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.


step 8

The 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.


step 9

Before 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.


step 10

The joints were then heat shrink sleeved to insulate and keep out moisture.


step 11

Wires were then PVC tape wrapped over the join to provide mechanical strength for the somewhat delicate wires of the visor.


step 12

For 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.


step 13

With 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.


step 14

Cable from visor coming out through hole behind light.


step 15

If 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.


step 16

Try 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.

This 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. 


step 17

The 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.


step 18

Both the grounds are connected to a ring connector and grounded using the earth point behind the interior light.


step 19

The lives are again using a crimp connector joined to the permanent live on the interior light.


step 20

The wiring can then be tucked into the headlining and the interior light replaced.

stand back and admire your work.
