It is not fair to question dohnjoe's reply. I watched the video you posted after my request and your blower had previously plenty of force (yeah, noisy too). Then you said you changed only the fan with a new identical one without disturbing anything else and... no air flow. So you tell us what's wrong. You were there, we didn't see what you did. Guess who is to blame?

Yes I only took out the fan and replaced it and this fan has plenty of force too, you can hear it how it screams when it's on max, but it's barely blowing. I used two wires to switch +- on the connector to see if it's spinning in the wrong direction, but it's not because it was worse when I switched + and -.

 

The motor doesn't have the blades mounted wrong, so I was just asking what else could be wrong. It isn't obligatory that it's something I touched. Maybe another thing ? I really don't know.

 

Is there any shutter for air that could have locked itself in closed position ?

Hey man...

Ihave the same problem in my ride....

But I solved it by take the blower out and make a new bearings for it ....
