Your problem is the ignition switch. Either the switch is bad or if the switch is mounted on the steering column, it may be out of position causing it to only energize the ignition circuit but not energizing the accessory circuits.
It depends on the vehicle , but some common are , the speedometer, gauges , the door locks and power windows. Also the interior lights and radio.
Dead battery or a broken battery wire
Sounds like a loose ground wire. Vibrations of the vehicle cause intermittent service interruptions.
Blown fuses for these accessories most likely. if not you have an electrical gremlin good luck.
you will have to take your dash apart from were the gauges are all the way to the radio
Blown fuse
Possible sign of a bad alternator not producing adequate voltage. Have your local auto parts store check it out. Most likely has to be replaced.
Start by checking all your fuses under the hood and under the dash.
Looking at the front of the factory radio you will notice two slits in both lower corners. You are supposed to purchase a radio removal kit from Mercedes. But I found that you can use two metal nail files or feeler gauges. Slip the files or gauges into the slits, this releases the side clasps. Leaving the files or gauges in place you should now be able to pull the radio head unit straight out towards you. Do it slowly to make sure you do not break the wires connected to the rear of the radio. Now you can disconnect the wiring harness behind the radio.
yes electricity is used in cars, because how do you think the lights work but of course you don't pay bill for that. It is what ignites the gas, runs the gauges, in some, the speedometer is electrical, power seats, power windows, radio, GPS.
How can the use of waveguides running from the antenna down the radio tower to the radio equipment be avoided? give two solutions to this problem
