I took a closer look at your photo and it appears that your front window switches don't appear to be self-centering, which can activate a relay coil, but have no power to move the window. There's a control circuit and a power circuit in each switch. That would account for a battery drain and a sound, but it may not be the circuit breaker you're hearing.

This is a new one on me.

One last thought. Check where the black wires come from on that plate. Only the wire from the harness should go to the grounded side of the circuit breakers. The other stud is for ground wires from motors, lights and lighters. Mounting any of them on the wrong stud leaves the circuit protection defeated. The black wires can easily be confused. Doing it wrong can easily cause a fire. Normally you think of circuit breakers that open the hot wire, but on a car switching is how the circuit accesses a ground.
