i am having a stranger problem with my heater. since it doesnt get cold any more i have no reason to use my heat, but, when driving down the road and wearing flip flops, heat is coming out of the floor vent. its no just a little amount of heat, its enough to actually make my foot pretty hot and uncomfortable. the power is off and it still does it, I have no clue what is going on, so if anyone can help that would be great. thanks guys.
