W124 air vent thumb-wheel bulb blown

[J-Scho]

I've tried searching but not found a definitive answer relating to the W124.

Basically the thumb-wheel on my passenger side air vent does not light up like the centre and drivers side do. How do I go about changing the bulb?

Almost forgot - what sort of bulb is it too?!

Take a small torch and with the vent flaps in a central position look for 4 plastic clips protruding thro the sides of the vent into the centre duct 2 on the top 2 on the bottom. move/depress them while wiggling the housing to free it you should then see the bulb holder. use the old bulb as an exemplar get one from your MB dealer.
