Thanks for all the good advice!!
I spoke with the rebuilder of the control unit about the problem and he said he has never heard of such an instance and the wheel can only be installed one way, he did offer to recheck the controller for me at no charge but I am not so sure this is the problem. I had previously checked the airflow across the car temp sensor... but rechecked it again... still good. I am now going to perform the checks in the article Q posted... hope that leads me somewhere

Thanks again for all your help!!!
