I have a problem with my '01 heater selector sending the heat where you want it. The air is hot, but when I select the heat to blow out near your feet, it doesn't make it. The defroster is bad also. If I choose it to come out of the A/C ducts it works fine. Seems that is where it will only work. The vaccumm line is connected to the canister in the bumper area and I think the vaccumm of OK. Has anyone had this problem? Any idea on ther fix? Thanks.
