I was just reading your thread, and wondered if we have the same problem. Please read the following thread:

I just called my mechanic and they are still running a series of tests on the car. They are considering replacing the climate control unit to see if that is the root cause. If it does not fix it, they will put in my old one back.
I would appreciate any comments from you.
Thanks.
