HELP!! I have a 2005 infinity qx56 the rear ac isn't blowing but the front one is. What should I do?????

There is an info button. Press that button repeatedly until you get to maintenence. Once there, use the directional knob and toggle down to oil and press ok, from there it should either give you a reset tab to highlight and press ok, or highlight the mileage bar and toggle left until it is back at 0. If you have any trouble let me know and I will walk you through it.

More than likely, you have a blend door actuator problem. Locate the faulty actuator under the dash, usually on the firewall, and replace.
