LZ Engraving

It is all doors and sometimes the drivers window rolls down. I'm not familiar with scanners but I know electrical troubleshooting, I just need a schematic to get me started. I'm suspicious of the key switch, but I can't duplicate the issue when the door panel is removed for some reason. I'll just have to leave  it off until it starts acting up again.

My doors are unlocking by themselves. I notice it most after entering vehicle and using the key to get in. Thought it was a bad switch in the lock mechanism but I'm not sure. Does anyone have experience with this issue or schematics on the door locks?
