i did do the modification on the front hose as listed in the files
section. mine however wasnt sagging much and wasnt i believe
restricting the flow. it was while doing this that i found the back
hole on the furnace box open that was blowing the air out also. as
stated covering this hole greatly increased the air flow to the ducting
by the bench seat. anyone else found this hole uncovered? i wonder if
the furnace was worked on previously and this was inadvertently left
uncovered.
