Manual controls (push button) without dual climate control.
Mode door actuator is high up on the drivers side behind the instrument cluster.
Need to lie on your back with head on accelerator pedal and look up high. I had to remove the brake pedal switch to get my hands up there. Also pulled the cluster out to get to one of the bolts.
Search the last couple of pages or my previous posts and you will find a link to an external site that has a step by step.
Inexpensive part but awkward to swap it out.
i have dual climate but i know exactly what your saying in my car its pretty much on the side of the radio under the drivers side i dont think its as high as the single climate control ..still in an awkward spot though...problem fixed itsself so i will leave it alone for now lol
