I have an issue with the climate control and damper doors and not blowing where it should. If I pull the fuse to recalibrate the A/C will blow where it should . When I turn it to defrost it does what it is supposed and sometimes it will go back to A/C correctly sometimes it doesn't and it blows the wrong places. If I pull the fuse and reset things it works correctly. It seems to get confused very easily.

I am thinking the climate control unit has an issue. But I have been wrong on things before. Any thoughts and suggestions would be appreciated.
