Having problems with your 2005 Nissan Maxima ?
I have a Nissan Quest 2001. The front air conditioning works the mid section does not, it just blows hot air.
I know this is late and hopefully you have this fixed, but the problem is probably the air diverter door control. There are 2 doors, 1 front, 1 rear (middle) and they are adjusted by a single control to balance the temp front and back based on the controls. If this goes out, you either are stuck with hot air up front/cold air in back or vice versa. You can try manually moving the doors to see if they are stuck (in the duct work) or test the actual control circuit. Check your tech manual for how to do it.
