speedometer lighting

hello!

i drive a 262, which panel-wise is just like any 200 series volvo. the
problem at hand is speedometer lighting (i mean the light to lets you
see what's on in the dark; the warning lights all work). it went off
and no fuses are bad and everything else on the panel (except for the
clock) still lights. the only thing that comes to mind is that the bulb
may be wrong. first of all, is there a small bulb which lights the
speedometer and which can go wrong? if yes, how can it be accessed the
easy way? i have been doing some work behind the panel (wipers) and it
was really messy, still i couldn't figure out how to remove the
speedometer after having released the two screws just above the driving
wheel.
if no, there is no bulb, what might be wrong (given that clock lighting
doesn't work as well)? well, at least where should i test the
electrical current to locate the problem. im not with an aptitude for
electricity, so im not sure if the latter question is approriate.
still, any advice is welcome.

regards,
Ingars

What model year? First try connecting all the wires on the dimmer
rheostat together.
Up to 1980 there are 3 bulbs clipped to the underside of the dash, the
cluster has to come out to access them. After removing the 2 screws
you're talking about, disconnect the speedo cable, then pull the whole
cluster out. There's spring clips, so it needs a good tug.

while blind touching behind the cluster to see where should it be
released. i accidentaly came across these bulbs. they're broken.
nevertheless, im quite sure i will not be able to put them back without
removing the cluster since i don't know where they fit in.

sorry, if its a stupid question but its the first time i try to remove
the speedo - is the speedo cable the one which is right behind the
actual speedometer? is there only one cable in total to remove before
pulling out the cluster?


, then pull the whole
cluster out. There's spring clips, so it needs a good tug.

where exactly are those clips located? on the sides of the cluster? on
the top? should i try to release them and only then take the speedo
out? should i rather push the speedo from behind or should i pull it?



greatest thanks to every tip,

regards,

Some of the speedos have two cables, I'm not sure if ones that old do
but in the early 80s at least there was a separate little (worthless)
box which would turn the Lambda light on every so many miles to remind
you to inspect the emission control system. If this is present you can
yank it and throw it away, it puts more load on the odometer gearing and
can strip it out. Otherwise there's one big mechanical drive cable for
the speedo.

The speedo cable is located dead center on the actual speedometer.
There are a bunch of wires too, but they have some slack and can be
disconnected after the cluster is moved forward.

The spring clips are on the top, there's no way to release them, just
pull. You may find it easier to push on the back of the cluster
instead.
