All 3 functions use the same wiring and bulbs to the rear of the coach, right?
You are correct. I need to go look at the wiring diagram to refresh my memory. I believe that the brake switch feeds the turn signal and 4 way flasher assembly on the steering column and then the wiring goes to the rear lights of the coach. So you are probably correct that the rear bulbs are not shorted. But... shorted bulbs and sockets are very common, so I might take them apart anyway just to make sure. I am wondering if there is something else besides the brake lights drawing power off of the brake switch.
There is a kill circuit for the cruise control also on that switch and it is wired to the brake lights. You might want to find that cruise control circuit and disconnect it. This might just be a bad / shorted brake light switch. I need to go look at the wiring diagram before I say too much more from memory and find out later that I am wrong.
