Climate Control Dead
2004 e55 - I first noticed the digital display was not working but the cc functions were all working fine. A few days later driving it at night the lights on the climate control were blinking/fllickering intermittently but the digital screen and functions were working properly. The next day I started it up and the climate unit was completely dead. Today in the garage I turned the key to acc and noticed the lights around the knob were illuminated but as soon as I started the car the entire unit went dark. I took it apart and checked the wires and it looks good. I also looked at the ribbon cable above the rear view mirror (which I have replaced before in a prior e55) and that too looked fine. The fuses, specifically 76 I believe, looks good as well. Because it was intermittently working before I am guessing it is in the wiring but really don't know where else to look. Any guidance would be appreciated.
