I'm a new owner of '98 230. I've taken the dash and console apart for refinishing. Before reassembling the dash, I checked all the instrument cluster lights. They are all good now (I replaced two lamps). However, with the lights on (either parking or headlights, engine running or off), I'm not getting any illumination of the odometer and trip odometer (the display is fine...just no illumination...so can't be read at night). The lights for the similar clock and external temperature displays are fine. I rechecked the lamp for the odomter/trip odometer and it's fine...I even checked it with the lamp installed in the cluster (using straight pins in the clips of jumper wires from a 12 volt battery). So...I disassembled the instrument cluster thinking I may be able to get to a bad solder joint (or something). Everything on the printed circuit board looks fine (as near as I can tell...I did not try to separate the instrument faces from the board). Trying to follow the printed circuit for the lamp, it appears (to me) that the circuit is not connected to a power source, but I could be wrong about this. If this is the case, the lamp wouldn't have been functional from the factory. What are others' experiences with this display? By the way, my car, as I suspect is the case with other early SLK's, has the "LIM" display (just below the center of the speedometer) which I understand is not functional on US cars (even though my car had a lamp in the PCB for this display and this lamp is connected in parallel to the lamp for the odometer/trip odometer display. So, bottom line, is this a quirk of the early cars (i.e., no illumination for the odometer/trip odometer) or do I have some sort of fault in the instrument cluster PCB that's not delivering power to the lamp?
