Rear air isn't coming out of the vents on 07 Infiniti

Customer Question

Rear air isn't coming out of the vents on 07 Infiniti QX56. I can hear the blower running, it will change speeds but no air comes out of the roof vents.

Hello and welcome to JustAnswer!

There are quite a few things that could be causing your lack of airflow. It could be a physical blockage from foreign debris preventing air from flowing, the blower motor may not be running full speed, or there coudl be a mode door issue. The mode door is the door that controls the direction of airflow. When changing modes do you hear a change in the rear heater box? Does the blower motor appear to be running at full speed?
