Sounds like you have a vent stuck and your heater valve is stuck open also. Check the valve first.
Over the past few weeks, I've begun using the air conditioning as the temperature is going up. I've noticed that even if the main vents are pumping out cool air, I am getting heat from the front seat foot vents, as well as the small triangular vents aimed at the side mirrors.
Admittedly, I know next to nothing about the heat/ac system. Is there any reason why these would be providing heat, while the other vents are blowing cool air?
Thanks

There is a color code red and blue dial adjustment for middle dash vents. If you have them on cool or blue it would feel colder then foot vents but you probably know that right?Originally Posted by ElNormo

probably a stuck heater valve, sometimes you can smack the valve and get it to unstick but it will stick again evenitally, it's right next to the fuse box
all america wants is cold beer warm cat and a place to take a poop with a door on it
well ... I just wonder about the rubber fittings inside the valve they can't resist the coolant properly also coolant help cracking the rubber seals quicker, I fixed my valves on the E31 and added a thin layer of thermal silicon rubber to prevent water running inside the solenoid stopping it from functioning.
