Yea leafs and other debris can get in and cause the noise. Remove the blower, thoroughly clean the fins and reinstall. This should take care of the noise.

it is either a bad switch or window motor. finding a wiring diagram and shooting power to the correct wire will identify whether the switch or motor is faulty.
