There are actually three fuses to check, the "stop lamp" of course and the "ECU 4" both in the e/r fuse and relay box, plus the "pdm 2" in the I/p fuse box.
There is also a stop signal relay that could as well be bad if all those fuses are okay and have power.
Here is the brake lamp wiring diagram. I see the ESC module in that diagram, so when you find out what is causing the stop lamps not to work, I suspect you will also fix that ESC problem as well and most likely get the cruise working again as well, because it too is related to the stop lamp switch.
