I had similar symptoms before, when i had my temp dial set to the three blue dots and my tempersture set at the at the lowest, my top vents blew out cold air fine. The problem was I kept feeling hot air coming out from gas pedal area. A friend suggested to look over this thread, so I replaced my water valve. Problem solved.
I have not felt as much heat from the foot area for a month or two, but a few days ago, with my climate control set to auto, and my sandals on, I felt warm air coming out from the area that is to the right of the gas pedal. The air coming out was not as hot as before I changed the water valve, but with the temperature and dial set to the coldest, warm air is still coming out from there.
Any thoughts on what the problem is?
