Climate Control Problem - LX 470

Well, these forums aren't as well travelled as the Jeep forums, but I'll take a shot.

I am having a problem with my Lexus Climate control. The driver side is blowing warm while the passenger side is blowing cold. It's not an independantly controlled system (at least not from the dash) so I am wondering if anyone has any insight into how the system does the air mixing and how one side could be cold and the other hot?

I asked my buddy with access to ALLDATA but he said that the schematics are not very intuitive and that I should come down and look at them myself. In the meantime, wondering if there's any help here?

Thanks

HKM I have a 2007 lx 470 with the same exact problem. - warm driver's side and freezing pasenger side. My wife has to ride with a blanket around her legs while I am toasting. For a $70K vehical, this is unacceptable.
