[QUOTE="MacGuyver, post: 457929, member: 18877"] This has bothered me as well. While there are two 'doors' one for the heat / cold that typically gets called the blend door. There is also the gate that directs the air flow to different places in the vehicle. I'm unsure what to call that one, beyond the 'directing gate' or some such. One thing I have heard is that because of the way the air passes over the heater core the lower part of the core gets directed to the driver side and the top is the passenger side. So as the core gets more crud in it, or the exterior gets dirty, it tends to do it from the bottom up. I don't know that this is truth, but it gives an explanation that makes sense, probably. I'm unsure how you would clean the exterior of the core, but internally would be a super flush. Chrisfix has a video on it. I hope to do one this summer, perhaps for the whole system. [/QUOTE]
