It goes under the passenger side wiper cowl. This will have to be removed. If you do this, make sure that you have the piece that did not come stock in these that diverts water away from the cabin intake motor area.....if you dont know what this is just look at the No more water in the floorboard take 2 thread in the how to section. this will also have pics of the area, how to take the cowl off, and where the cabin air filter should be. It also has the gm part number for the water diversion plastic piece(it is literally three or four dollars) this may save your heater/AC blower motor as well.........Thanks, but where do I install the cabin filter?
Im saying this in the best way possible. where the hell is that or do you add it?
what are the chances of my 03 even having one? and is the stealer ship the only place you can get that piece of plastic that fixes the water in the floor boards? i figure if im that far into it I might as well do some good.
