Power window switch sometimes not working

"Hi @ypoop ,

Here is a video that shows how to remove the window switch console of your vehicle so that access can be gained to the wiring at the back of the switch unit.

Here is a video that shows how to determine if the problem is in the switch unit or perhaps in the wiring to the window motor or in the window motor itself. (This video is not for your model vehicle as far as I know, rather it shows the testing procedure to find where the problem might be)

Hopefully this is of some help to you in tracking down the problem"
