So, my rear passenger windows stopped working. Once in a while they'll magically work. My usually mechanic, without any serious diagnostic time, believes that it's a problem with the car's main cpu.
Obviously, that's a huge expense to fix a couple windows. I thought about

replacing the driver's window panel to see if that works, but don't want to go through the hassle or expense if that's not the fix.
Any advice? Here's the fault I get from my GAP Tool.

 

I would remove the switch and apply 12v to see if window actually works.
