mb C200 Elegance 2001 dashboard problem

[feli]

The light on my dashboard display suddenly goes off when I'm driving and the signal indicator lights and the power windows do not work any more.Before all this happens,I usually hear the fan of the AC running even though the AC is not in use.What could be the problem?The radio is sometimes affected.​

a bad connection of the wires..
that light u're talking ... it's the blue high beam light, right?
..have u been messing around (playing with the wires..lol) the radio lately?

ps. also, sometimes the key-transmitter doesn't work that well, right?

Thanks for the information about my problem.I have not messed up with either the radio or the blue highligt beam.It could be the wires which have a problem;I will check it up.My key transmitor does not sometimes work properly, I remove it from the ignition and fix it again when it happens and it starts.Could it also be the gas{refrigerant} for the AC motor which is finished and could be causing the problem?
