The left side of the instrument cluster on my '82 300D went dark. So yesterday I took it out to have a look at it. There are 3 little bulbs at the top behind the cluster but there are also 2 knobs close to these. Are there bulbs behind the 2 knobs? But my big problem is that I can't take the whole cluster out of the car because I can't disconnect the fuel and temp gauge connecter. How is it supposed to be disconnected??? There are also the individual wires going to the glow plug light, etc that look like they might be troublesome getting off.
Any help would be appreciated.
