Hi,
There is one circuit breaker for the right-side windows. It is in the body relay block .See pics 3 and 4 below and let me know if that is where it's getting hot.
Next, if that is correct, for now, remove the circuit breaker. If it fails, it can cause a fire.
For it to get that hot, I suspect we have a short. What I suggest is to first disconnect the passenger side, front window switch and then reconnect the circuit breaker to see if you hear it click off.
If it doesn't, reconnect the switch, disconnect the power window motor, and retest.
Let me know what you find. Note: Although a circuit breaker is designed to stop power in the event of a short, don't trust it. Remove it until we find the problem.

See pics below. Pics 1 and 2 are the wiring schematic for the windows. I added it as a reference for you.
