hi, i had just installed pioneed avic700bt and before i even got a chance to plug in the metra harness for the metra ac controls, the hvac unit shut itself off...now i have nothing on the hvac screen and no air or heat. Please help! i have checked the fuse for radio which is indeed intact since the pioneer works fine. Is there a seperate fuse for the hvac located elsewhere besides the battery compartment...any help will be much appreciated! ...FYI i have a 2003 g35 sedan

dont know if this will help but check the fuses under the steering wheel. Maybe there is a fuse in there.

as KKARMA said there's fuses by your foot rest. Check those i don't see why your hvac would go out. I just installed my avic-f900 on friday and everything works perfect just that i used the jdm double din
