Been fighting a parasitic drain every since I got the GX about a month ago. When doing some cleaning today, I noticed that the lights were on, on the master switch, with the door open and the keys no where near the truck. I am able to open and close the drivers side window at all times, but no other windows. If I hit the lock out button, the other lights go out. Right now I have the switch panel unplugged and will see if that solves the drain. Does this sound like it could be fixed with a new switch, or is this more likely a BCM problem?
