Q: Intermittent malfunction of electrical components - 2007 Mercedes-Benz SLK350
Ocassionally, after I have turned the key into the first position, most of the electrical components of the car stop working. These would be the AC, blinker, speedometer, tachometer, power windows and the gauges. This doesn't happen all the time, but when it does, it would correct itself after I restarted the car. How can this be fixed?
