I just got done installing the motor blowers yesterday then driving today I noticed it was making thepedelsvibarateand thefloorboard and doorvibarate on the passenger side. It also seems a lot louder. The fan doesn't to be blowing with as much power as the old one did either. Does anyone have any ideas of what could be causing this. Thanks in advance.

 

It's likely the wrong fan. They also should be balanced. You can plug them in and test them before installing them.

 

I'm pretty sure its the right motor I got it from fcp. How do you balance them?

 

The one I got out of a V70 had a weight on the fan. When I plugged it in before I installed it, the torque tossed it out of my hand so hold on tight.
