How about turning on the blower to blow all the crap out into the occupant area before you reinstall the new filters? LoL. so this model the arrow is not the direction of air flow but the opposite.
Does anyone knows is there is separate air fileter for the REAR SYSTEM? The reason I'm asking is because recently my front system stopped working and the reason was that the two filters behind the glove compartments were litteraly completely clogged with all kind of debree. That made blower motor to fail and trigger two 15A fuses to burn under the hood. So I know there was no way that rear motor was using the same filters.
