Rats! Looks like the window control ECU on my 456GT is toast. I have been working on it for two days and I have ruled out just about everything else. I have read up on this topic both here and across other forums, and I am fully aware that this ECU unit is... ahem... difficult to find. I am currently on the hunt and I can use any suggestions/recommendations you are willing to share on how to get my hands on one - possibly without having to pawn a kidney. Also, has anyone had any luck with places like ECU Doctor, etc. for this kind of repairs - if in fact repairing is the best (or only) option?
