Fan motor blowing hardly any coming out vents.
 

With ac or heater fan full blast can hear it but very little blows out vents. Nothing out rear vents on console. When AC is on the recirculate button can hear some clicking under dash. Any ideas where to start before tear into the dash?

During the last year I notied that my fan blows way less than before. is the blower fan dying? same issue here.
Before, it seemed to me that on high, it blow quite a bit of air. Now, on high, it will not blow enough to keep the car cool during summer, or to defrost properly.

Anyone else?

I can hear it blowing hard. Thinking door in vent system is stuck or broken.

is your cabin filter clean?

I will check. Hope that all it is. Still have to figure out clicking sound.

Well I took the filter out looked clean had some leaves. What I did find is one of the flapper doors was laying on top of the filter. I could see the housing was cracked in one spot so will have to tear into farther and see what is really broke then. Hope courtesy Nissan isn't to outrageous.
