I've been dealing with this issue for a couple of winters now and really want to get it fixed. Heat on the drivers side works as it should, but I have no heat on the passenger side (lower, upper, and defrost vents). There is no noticeable change in temperature when I change the temperature from 65 to 85. This is a 2005 model with climate control (aka fancy digital display). I took apart the passenger side dash, and it appears that all the actuators are working properly, so I'm a bit stumped. Anyone have any thoughts?
