2006 350z ac issue
it only happens sometimes but when i turn my ac on a little bit it will go full blast and in the middle it will go low then high again. I just replaced my serpentine belt but if i need to relplace the other one to fix the ac will someone let me know?

This is normal behavior if the AC Fan Speed **** is in the "AUTO" position (Or 1 rotation click from the off position). If you're saying the fan speed intermittently changes when using the manual speed selections, I suspect the problem is with the AC control unit in the dash (the board with all the control ***** on it). You can find these on ebay for relatively cheap.

Welcome- Just a bit of detail to add to Icer5160's post. The "auto" setting is automatic temperature control. Using this will allow the fan to go up or down as needed to maintain a desired temp setting. This system may be operating in other settings if the HVAC control unit (a small rectangular white box behind the lower center stack *****) is malfunctioning. There's no real way to test this unit that I know of- you usually just replace it with another OEM unit and see if the symptoms go away.
