Hello, we bought a Duc 280 as a camper a few weeks ago. Did everything without any problems. Only a brake lamp at the rear right was defect, so back tail light off and new bulb in, on the left side also immediately changed the bulb, lights again on and then when braking and blinking left flashed then the indicator lamp for fog lamp in the blinker clock and indicator in the rear flashing out and brake light flashed. Right side everything normal. So lamp at the back off, and the problem was strangely fixed. Then did a tour, on the way back blower failed. But don’t find the connection where I could measure what is broken there. And since a few days the control light for the passing light does not work anymore, however, all the headlights are on when I turn on, the instrument lighting no longer works as well. Light bulbs in the speedometer unit are all ok. What could that be again? Does he have some kind of electrical problem?
