Question Horn and Lock Actuator Issues

I have a 2010 Hyundai Elantra sedan, and I've had some recent issues that I was wondering if anyone else has experienced. It started with what appears to a be a failing lock actuator in the rear door on the driver's side. It would periodically not lock with the FOB and the horn wouldn't beep in those instances (I've since ruled out the FOB as the issue). Then the horn seemed to die about two months ago. I replaced the horn with a Wolo generic one from Advance Auto, which worked fine but then the new one died two months later. So I then replaced the horn relay along with all the horn fuses, but it still won't work.

I'm guessing there is some sort of correlation with the lock actuator failing, but does anyone know if a failed lock actuator can somehow short out the horn? I've never heard anything like that happening before, but I'm hoping to figure out the root cause so I don't have to take the front bumper off again to get to the horn only to have it fail again in few months.
Any ideas are greatly appreciated.
