A piece of plastic tube fell into the air con vent and now the fan motor makes a loud noise when you turn on the fan. It will subside after a while but will continue again when you make a turn or come to a stop! Where do I locate the fan motor and how do I get in there to remove this plastic?

Just to add, looking under the hood, passenger side rear, can you see the blower motor? If not, you will have to follow some cut lines, like gmac says.

My info says you may have to remove coolant recovery reservoir and vcm.

I wasn't trying to butt in, I just happened to be looking up info on this vehicle. Have a good day.
