Joe, you had better luck than I did. Do you think these modules are plug an play or do they require any 'programming'. I'd hate to buy one and assuming it is good, have it not solve the problem for lack of a programming requirement.
btw, the Mrs had to spend $100 to diagnose it and if they had had the part she probably would have given the ok to replace it. She has grown dependent on the back up aid and is contemplating trading up. That would be a horrible waste of precious resources. Whether you have the money, or not, to dump a 56k mile perfect car for a 1/10th of it's original cost would be a sin.
