It's not my fault if you didn't have it diagnosed by a live person who can perform tests. Do you really think we're psychic? All I have to go on is the information you provided which wasn't much. I never told you to replace any module. Based on their history of a high failure rate and on the lack of any real diagnostic tests, I suggested it was a likely item to suspect. Professionals perform all kinds of tests first to eliminate any other possibilities. It's rather hard to do that over a computer. Sometimes even the professionals have to resort to plugging in a new computer to see if that solves the problem. The difference is they can take it back out if it isn't the cause. That is one of the benefits of taking the vehicle to a shop and paying for the diagnosis.
It is possible one of the circuits that isn't working is shorted to ground and the computer is shutting one of its power supplies down to protect it. I hope you don't think I can figure that out from where I'm sitting. Most of the people on this site are trying real hard to help do-it-yourselfers such as yourself. A lot of the people who post questions here have no idea how to perform any of the necessary tests, and they can't even provide a clear description of the clues and observations, yet when there are dozens of possibilities, we are expected to know exactly which one of them is the culprit. Boy, if we were that good there wouldn't need to be any repair shops with highly trained master diagnosticians. Some mechanics attend many days of update training every year to learn how to diagnose these modern electrical systems. I wasn't a student; I was the teacher, but when it came to diagnosing a specific problem, we had the vehicle and test equipment in front of us. That's a necessity you didn't allow me.
I'm grateful you were willing to make a donation but I have never heard of anyone having a problem getting a refund. We don't even get to know how much you donated. Our responses come from our desire to help you even if you don't make any donation. I understand that a lot of people are hoping to find answers here because, like me, they are unemployed and money is tight. Most of us work just as hard to figure out answers for people who made no donation and fortunately most of them are grateful for the effort. If you can't figure out how to get a refund, (and don't read anything into that. I never tried so I don't know the procedure), I will gladly contact the site owners on your behalf. You may contact me directly if necessary.
