Having problems with my smart window on my 2013 Challenger R/T going up and down all night long as if I am putting my hand under the external door handle. This is causing the battery to go dead. Took it to Dodge and they said that the problem is the door latch. They want $480 for the part and $200 labor. Has anyone else experienced or heard of this problem? I don't see how it can be a door Latch...maybe a window actuator or something.
