adaptive head light problems after car wash

Trying to troubleshoot my problem. my passenger side light went out after car wash, and I found the ballast had water in it. I removed it dried with a hair dryer and it worked fine. replaced the headlamp and then the driver side stopping working. I figured ame problem, except I swapped every piece ( xenon bulb, inginter, ballast even the adaptive controllerS) from side to side with having the same issue with the drivers side. I even heat shrinked the tiny 20 gauge wires that insulation flaking off of them. Before I understood the lcm would rest if you pulled it out, I sent a used lcm and had it re programmed for vin/mileage, and that worked great. However, I still have to pull the lcm out to reset it after each time i drive. My drivers side headlight is always the culprit, i v'e switched ballasts, igniters and even adaptive modules from side to side, every time the light comes on after resetting the lcm. I can drive for a half hour plus with both lights working. But after i turn off the car, remove the key , and try to use the headlights again the drivers side will not work without removing and allowing the lcm to reset. It's driving me crazy, I really hate this car Sadly it only has 64k on it.
