Changed the cabin filters today and after removing, and before installing the new ones, the fan motor began vibrating. The vibration increase with fan speed and shakes the whole dashboard. Also makes a tinging noise at the very low speeds. Didn't do any of this before. Same when I put in the new.

Is it possible some of the old filter fell down on to the fan to make this happen? Not sure where the fan blades are exactly, but assume they are under the filters.

Any ideas of what I can look at before I spend $ on repairs.

Thanks,

Chas

Found the problem. Totally clogged fan motor. See pic.
Very difficult space to remove, behind the glove compartment (you don't have to take the glove box out) but only 3 screws on the motor and 1 holding electric wire.
Left it connected because the spot of connection was not really visible and much easier.
The weight of the trash in the motor was creating the vibration.
All is well now.
