My sedan at the moment has no power going to the A/C controls and none of my gauges have a reading. No MPH, Tach, Fuel, or Temp readings. Also my Brake, ABS, and VDC lights are all on. No CEL though. Can anyone help?

 

It sounds like all those functions are common to the "unified meter and A/C amp" which is detailed here in the manual: http://www.nicoclub.com/FSM/G35/Seda..._Sedan/mwi.pdf (Its operation theory is detailed in the early parts of that chapter of the manual, but the actual troubleshooting diagnosis begins on page MWI-49)

I would look for the obvious things first, like no power going to it due to a blow fuse.

Good luck.
