Hi, the lights in the instrument cluster on my 1987 W126 300SE do not
seem to work, neither does the light that would normally illuminate the
gear lever. The reostat makes no difference and there is a warning lamp
on the dash for a burned out bulb. I think that the light is telling me
that an exterior lamp bulb has gone and it is nothing to do with the
dash board/gear stick. It only comes on when the head or side lights
Any assistance gratefully received.
The warning lamp is not related to the dash light failure. The latter
is almost certainly caused by the rheostat as all the electricity
for the dash and gear lights must go through it (to be dimmable)
and when (not if) they fail all the lights stop working.
The rheostat is not particularly cheap but if you are halfway handy
you might be able to repair it. I fixed mine (AFTER buying a new one,
doh). You have to pull the cluster to get it out and you probably
ought to replace all the bulns as long as you're in there given the
age - they're gonna be pretty dim by now. These bukbs are not ones
you're gonna find in autozone but aren't expensive at the dealers.
