My passenger side window doesn't work on the auto-up function. All other windows does auto up and down but just this window all of a sudden. also, when I close it, it comes down slightly automatically. did I accidentally change the setting?
You need to re-sync the window mechanism, sometimes when you press up and down very quickly, the window and the mechanism un-sync to prevent mechanical failure.
To re-sync your window: Using the driver's window controls roll the problem window all the way down (press the switch down, and keep button pressed for 5 seconds while the window is down). Then release the switch and roll the window up ( lift the switch up and keep button pressed for at least 5 seconds.
The auto roll up/down feature should then start working.
This is from memory, I am 90% sure this is the method, the lengths involved might be a bit different, but it is covered in the manual if this doesn't work.
