My 2003 G35 sedan has a strange problem I hope you can help me with. The console switches/ controls for the A/C and radio do not work. The A/C works fine however the fan defaults to high which freezes us out even in Florida. The radio controls on the steering wheel work however again, those on the dash do not. Is this a fuse and if yes, where is it?

 

I had a similar problem in that everything in the center console would not light up and the A/C was set at the default and would run at that
It turned out to be a fuse in the box next to the battery in the engine compartment
check that

 

you'r gonna need a new AC/radio circuit board. common problem in the 03.

 

Thank you, I hope this is all it is.
