Hi all, my 2000 Navi has the A/C and Heated seats but it seems as if the seats do not heat up as much as they should. My friends have other vehicles with heated seats(typical hi/lo only) but their "hi" will burn you up in no time. i can put my heat on "5" and it is only warm, not the hot that i experience in my friend's vehicles. I blew the filters out with an air hose but didn't really help. any ideas? thanks
