get a new head unit from the junk yard. I had the same problem. Smack the front of it and I bet it straightens out for a bit.

Thanks but what is the head unit

[jacuzzo]

the head unit is the box with all of the knobs on it. It is screwed into the dash and has two connectors. I am assuming that you have the computerized version. I have found that when mine went bad I could wack it directly on the fan knob, straight back with my travel mug, and it would pop back into compliance. But of course with all easy answers in life this one runs out too. In my experience it is cheaper to go to the bone yard and try your luck until you get one that does not need to be wacked now and again.

Of course, for all I know there could be another underlying problem.
