Hello guys! Can anyone assist me with a no power problem on the passenger side of my vehicle listed above? I can't control the window or the lock on that side from the driver switch also. The driver side switches are fine. Thanks in advance guys.

This happens when the passenger's side door module goes out. To be sure let's do a CAN scan which is the future of automotive repair. You can get a CAN scanner from Amazon for about $30.00. Here is a video to show you how and a link to a scanner from Amazon. I have included the instructions on how to change the PDM out in the diagrams below.
