Nissan Repair: 94 Nissan Quest, nissan quest, air flow

Question
There is not air flow from the  vents in the back of the van, I think the blower may need to be replaced? The switch to move the air from the bottom to the top vents seem to work but air still does not comes out. What is your opinion on this problem.  

Answer
Gus,

If there is a seperate blower, and I think there is, I would be checking it for function.  Take the cover off and see if the motor spins and if it does you can gcheck the circuit by powering it.  If it is not working I would bet the fan is defective.
