Window Open message after Tints
So I had just gotten all my windows tinted, and it was about a 3-4 hour process. When I got the car back, my dashboard had a CEL, and the Trac Off kept coming on. No matter how many times I turned off and restarted the car, the same issue followed with the "Window Opened" notification that also wouldn't go away.
My solution for the CEL and Trac Off light was to just disconnect the battery for 10 minutes. That took care of the CEL and Trac Off light.
For the "Window Opened" notification, I had to wait the 48-72 hour period for the tint's to have stuck on well enough for me to open/close windows.
Afterwards, I rolled all the windows down all the way, turned the car off, opened the door. Then closed the door, and turned the car back on, rolled all the windows back up, my passenger rear kept rolling back down after reaching the top, so I didn't use the automatic close. Once all the windows were closed, I turned the car off, and opened the door to look for the message, and it went away.
Has anybody ever run into this before? I found 1 thread on the ES forums where a similar situation happenned

It sounds like the position sensor was off and sending a bad signal to the computers. I am guessing while installing the tint, the person manually lifted or dropped the window a bit manually so that the sensor didn't register the slight change which threw everything off.

The CEL and Trac light comes on if the battery is completely drained when you try to start the car again with a boost or whatever it will show. I forgot what code it is but once you clear it and drive the system will be ready. Same goes for the Trac light you just have to drive it and it will go away. Pretty much the tint place drained your battery completely, Some tint places will either leave your car running so they can operate the windows without killing your battery or some will just use a battery tender to juice it up without the motor running.

When you see the window roll down right after rolling up, that's the Jam Protection function at work.
As the motor amperage increases, the ECU perceives that the glass is hitting something, like a child's arm, and rolls the window down so the object and glass are both not damaged.
Whatever the tint material is, it's causing enough resistance on the glass going up for the Jam Protection to activate.
You could try to recalibrate the Auto window and see if that cures it.

I think I must have recalibrated it when I was fiddling with the window controls. I don't have anymore issues anymore, and everything is as intended.

I think to calibrate it you use the manual function of the switch to close the window (so not pulling it all the way to Auto), then when it's closed you pull it to Auto and hold for a few seconds.

My guess is the tinter stuffed the seals downwards and this puts pressure on the window when the tinter rolls up. it's not the tint, but the act of stuffing the seal. he does this so he can get good access for his squeegee. i have experience tinting windows (for fun) so i know the process. not a biggy.
