Dash Light Bulbs

Dear Forum:

Great forum, I have always gotten good information here.

I have a 1996 C-280.

Two problems today, first: How do I remove the dash or otherwise get to the intrument lights? I have a burned out bulb that needs to be replaced.

Second, my gas guage is now intermittent. When it is working it reads correctly, but much of the time the unit is just dead, as in the needle reads empty. What is the most likely cause of this, and is there a fix?

Thank you all so very much for your assistance,

Chuck
