'14 GT Power Window issues
Hey everyone, I'm having an extremely annoying issue I'm hoping someone has the answer to.
Purchased a 2014 GT/CS with 50k miles, with an extended bumper to bumper warranty from the dealer.
About a month ago I started having issues with the driver's side window. It rolled down by itself and wouldn't go back up until I slammed the door. Eventually it wouldn't go back up at all unless it sat a few hours.
Took it in to the dealer and they said no biggie, power window motor was bad, as well as the relay and the switch, so they changed it. Worked for about a day and began going up and down on it's own until eventually it no longer did anything.
Took it back again and they said whoever put the motor in didn't do the reset properly and in doing so had messed up the motor again, so it had to be changed again. Fine, whatever.
After the second motor was in I didn't make it off the lot before it started messing up. Went back in and they said they'd check it, gave me a rental and sent me on my way.
Two days later they said the ground wire was bad so they changed it and it was doing great. Picked it up and indeed it was doing fine for three days.
Backed out from work and it started the same issue again. Took it back and it's been there three days and they have no idea what's going on with it. I've searched on here, Google in general, and posted on Reddit with no answers.
Anyone have any idea what it'd be? About two weeks prior to the issue I had exhaust put on but I don't see how that has anything to do with my problem.
Thanks for reading!
