Call them to update module, waited several days and called them, I was told they just recieved it. They would do it very soon. After three days they called and told me it was burnt up. They quoted me a price for a new on, I said fine. After another 8 days I recieved it and had same problem. I took it to a GM garage. The fellow was a friend and worked it in for me..He found a broken wire a mouse had ate and the new module was bad and wrong numbers on it.He installed a new GM Moudle and the auto ran find.
The new GM mondule was 240.00 less the the one i got from them. The GM tech feel that the only thing wrong was the broken wire. I feel he it correct. I call Module experts twice and could not get a thing from them. The are a bad group
