Electrical issue?
I've got a 2012 Hyundai Tuscon, and it's having what seems to be a host of electrical problems? I am not a car person at all, but trying to learn, so please excuse my ignorance.
Issue One: The back passenger door will only intermittently lock via the key fob, or the driver control to lock all doors. If I manually flip the switch on the door, it functions fine.
Issue Two: All passengers have full up/down window control from their seat, but the drivers controls for the same windows only function intermittents. The driver window functions properly. The front passenger, I need to reach across the car to roll down, but it rolls up fine, that's pretty consistent. The back windows, sometimes they work perfectly from the driver's controls, other times the up and/or down fail.
Issue Three: The interior light intermittent comes on while driving. Usually it occurs when turning right, other times when not turning, and many times I turn right and it doesn't trigger.
Any suggestions on what to start looking at?
Thanks!

It sounds like your 2012 Hyundai Tucson has a few electrical problems that you can start troubleshooting.
For the back passenger door that only intermittently locks with the key fob or driver control, the issue might be with the door lock actuator or a loose connection in the wiring harness. Inspecting the wiring between the door and the car body could help, as wires can sometimes get damaged over time. If the driver’s window controls for the other windows only work intermittently, but all windows work from their own controls, the master switch on the driver's door might be the problem. Cleaning or replacing the master switch could solve this issue. For the interior light coming on while driving, especially when turning right, a faulty door latch sensor or a loose connection could be to blame. Checking each door's latch and sensor, and ensuring they are tight and undamaged, may help. Additionally, checking the fuses, relays, battery connections, and grounds could rule out other common electrical issues.
Using an OBD-II scanner might also reveal any stored codes that could point to the root of the problem.
