Sounds like you have a short somewhere. When things get hot they expand. Could be that a wire has a bare spot and it's just close enough to something metal that when it's hot it touches metal and activates the light motors. Check the pivot points for the headlight doors. That wiring moves and flexes every time the headlight doors open and close. HTH. -Jim
