Does anyone know (or have links to sites on) how to access / replace the dash light bulbs for a) the headlight control switch and b) odometer?

Thanks.

The instrument cluster is removed by mercedes special tools or in my case
a bent coathanger. I remember the lights being in plain view from the back.

I believe to access the headlight switch you do it from either below by removing the carpet panel held in place by 2 tricky clips and a few screws or from above by removing the vent held in place by 2 clips on the bottom inside of the vent released by inserting small flathead and prying up...and 2 screws on the upper part revealed by removing the speaker cover.

Thanks for the information!

how you disable the airbag and is it necessary? I thought it was a plug and play reaplce.

The instrument cluster comes out by using "hooks" you slide them in the sides turn 90 degrees and pull the cluster held by friction, the heahlamp switch is accessed by removing the parking brake handle housing, slide a small screw driver into the notch at the bottom of healdmp knob it will release. Thjen remove the brake release housing, loosen the big nut and the panel will come off, the bulb is plugged into the housing (light pipe)

I guess you don't have to disable the airbag then. Whew...
