I have a 2005 Sprinter 3500 configured as a 2006 Winnebago View RV. I have a problem with the dashboard gauge illumination. The gauge illumination flickers between no illumination of the gauges where the gear selector (and odometer & temp gauge) are brightly lit, to the normal illumination where the speedometer and the tachometer are lit up and the gear selector light is dimmed to match the brightness of the gauge lighting. This flickering is erratic, sometimes back and forth every second or two, more of the time the illumination is off and then flickers on occasionally. The dash light rheostat still controls the brightness of the gauge illumination (I can see this when the lights is working for a few seconds) and does not seem to be the cause of the problem. The flickering seems the same with the full headlight system turned on or off.
My first thought is this is a loose power feed wire or ground connection for the dashboard lights, but I don't know where exactly to look for such connections. My second thought is that if there is a light sensor that controls the dashboard illumination as being off during daylight hours and on during darkness, that this sensor or it's control may be malfunctioning.
Has anyone got ideas or experience on what the cause is and how to fix it?
Thanks
