The thumping from the blower is most likely something in the

blower cage. something probably got sucked out of the glove box.

the recirc button opens the max air door and could be the button or

the motor on the door itself. taking the glove box out will be the

easiest way to remove the blower although they are tucked in very

tight and it may also be necessary to remove the bottom bolt for

the dash to make enough room to get it out all the way.
