The back left side window will not go down. All other windows work using either the main window console on the driver door or the switch at the door itself. Only the back left window will not go down by using either switch. Main console on driver's door or switch at the door. Could possible issue be fuse, relay, motor or electrical connection?

Most likely problem will be a faulty window motor itself, not wiring. If you remove the door panel you can put a test light across the 2 terminals at the window motor and operate the switch and if the light lights up then for sure the motor is bad. You can also slam the door while holding the window switch down and see if that jars free a stuck window motor. Hope this helps
