Since purchasing the car second hand I had an intermittent issue with the one touch window operation on the driver side. Issue would manifest itself after attempting to hit the lock button right after starting the car (force of habit), noticed the window would go down normally then on the way up the one touch would stop working and have to be reset. I also was curious if this was caused by a weakening car battery. It takes up to a few seconds for the alternator to ramp up to normal voltage on my car, so I thought it was low voltage which would be exacerbated by attempting to use central locking right after startup but that turns out to be some kessy limitation. Well, I watched a video about the door connector being some innovative german thing where you can pull the tab up and disconnect the whole door harness basically and I wanted to try it out, and I noticed upon reconnecting the issue is gone! Could it have been oxidation on these pins!? I sprayed some CRC QD electronic cleaner on it and let it dry and reconnected it again to be sure. Happy the problem seems to be resolved for now.
update 6/27 the issue is back, got excited for nothing! lol
