Hello, my name is Anja and I am 37 years.. I drive a Renault Scenic BJ2001. Some time ago my daughter played around on the radio. Immediately after that the ventilation, air conditioning, windscreen heating at the front and the heating did not work. The display where the temperature etc was displayed no longer lights up. BUT when I blink to the right, the display lights up. The window heating at the back works. The switch is right outside of the others… If I have the light turned on I hope you understand what I mean. I was in two workshops. One thought, without looking at it, that the control unit was broken. That would be too expensive and would not be worth it any more. The other said that it would take too long for everything to be screwed apart in the front to see where the short circuit is. Do you have an idea ?? And you see a connection that My daughter was playing on the radio before that?
