Buzzing HVAC system

[MattB]

When I turn on my I30's HVAC system it will occasionally make a buzzing noise from the passenger's side not unlike a weed-whacker (only not nearly that loud) that will go away after about 30 seconds and not reappear until the car sits for a while before being driven again. It only appeared after I had the car washed, so I'm wondering if some leaves or something got blown into the HVAC system. Or is my blower motor failing?

Good guess on the leaves, but you will not know until your open the evaporator closet.

take the blower motor out and see whats going on.

How difficult is that to do?

not real hard, just take the glovebox out and its right there...
