Nissan Repair: Nisson qewst 2000, actuator, cold air

Question
Our van has a separate ac fan for the back.  When I turn on the fan it blows outside or (hot) air.  The front systems works fine.  but the back has stopped blowing cold air.  Any ideas?  I would like to go to the mechanics informed.

Thanks,
Penni

Answer
Penni,

If memory serves me correctly you need to have the control unit looked at as well as the blend door.  The system uses the same compressor so the back should be getting cold too.  The only thing that would make it not work, as you describe, is the control or the actuator that controls either hot or cold air.  It is called a blend door.  So, when you go to the mechanic have them check the control and the blend door for the back system.
