odd but if you think about it maybe vibration from years of use on door may have gotten to it. I have opened them up and the use very high reliability parts, so if anything its prob a cracked solder joint if the ECU is the issue. For fun try installing it again, I have had issues like this where I swapped the ECU, cleared right up, then reinstalled the old one and all is fine. Makes me think it could be a 36 pin connector issue as well.
