Climate Control/Blender issues. Full heat or full cold only.

My 04 has recently stopped blending. When the temp is set at "COLD" it blows cold, but when turned one notch to "65" I have full heat. I crawled up under the dash and it looks like when I turn the temp to 65 the blend door actuator pushes the door completely open. Has anyone seen this before?

Mine just chatters and gets stuck unless I adjust to full heat or full cold. Contacts on the blend actuator are worn out. Sometimes a cleaning and re-grease will buy you sometime, but probably time for a new blender actuator

I figured it out. I had pulled the kick panel under the steering wheel this summer when I installed a new stereo. I missed the little two wire plug and white flex air hose going to the thermistor when I reinstalled everything. I didn't notice the problem then because it was hot and I ran the AC at full cold. The first cool evening changed that... Hooked them back up and we are in comfortable air!
