Why does the windows go down & sunroof open when car is just sitting in driveway? It's happened several times!!! Getting cold weather & l don't want that to happen for it to snow or rain inside my car!!!

 

Youre electrical system has a short somewhere. Wires are touching that shouldnt it seems to me.You should be able to find a fre manul online and watch some videos on the wiring for both sunroof and the windows.
Did someone recently try repairing your car? Adding an alarm or radio perhaps?
Could be something jarred and made wires touch that shouldnt.

Should be an easy fix actually - just trace the lines...and repair the connections.


Or it could be the switch(es) have gone bad, and/or the control box.
Theres tons of videos that go over sun roofs and window wiring on youtube.

My best guess would be inside your door panel. Wish I was there I have a power probe. Would be easy to detect.
Good luck
