i wonder if its going to make its way down to a point that it may get trapped/interfere with the mode doors (the ones that open/close) to balance the air?
the other option to consider- is removing the BLOWER MOTOR- and maybe trying to see if you can see the item thru those tubes.
The blower motor is on the passenger area. right behind the glove box.
If im not mistaken its actually easy to remove the motor- as it drops right down.
Theres a post around the lambda forums with pics on how to remove the motor...
