so... i ran the hose upwards, lifted a semi-rotten thing that i suppose was a foam filter on a plastic mount, and pushed the hose in there. turned the vac off and i can hear the hose rubbing just under the dash, a few inches below the glass. its obvious where that goes.
then i tried again as shown it the picture where the crap builduo is supposed to be.
took a few pics of that:
stuck the phone where the fan usually is, faced it left and took the shots. somehow it seems im supposed to clean the crap BEHIND the radiator on the pic?
