93 Bounder Parking brake
I have a 93 Bounder 34J 454 and the parking brake light is on.
I wanted to replace the light switch and I did not found any switch for auto park.
It is like my rv doesn' have auto park. The parking brake work , I did not see any of the components of the auto park under the rv.
If that possible?

Unless you have yellow Knob somewhere around the driver's position to release the AAPB, you don't have one. Not ALL P32 chassis were equipped with an AAPB-it is dependent on GVWR.
If you don't have a AAPB, then you should have a manually applied PB, either hand or foot applied, and that system could be activating the light.
Good luck finding the source of this warning light.

Our 94 Bounder had AutoPark, no knob. Put it in park and the AutoPark went on, shift out of park and it released. Should be a tank and pump on the inside of passenger side frame rail, rear of the trans. Cable from there loops up and over into the mechanism where the cable from the foot parking brake comes into. A 3rd cable comes from there and into the driveline brake on the rear of the trans.
Possible the system was removed, they're not very reliable.

There are pressure switches to maintain the proper pressure in the hydraulic system. Common failure point is the RGS, Rotten Green Switch, when it fails the brake is applied all the time and the light is on. When ours failed I just disconnected the wires to the AutoPark system so the pump didn't run and the light didn't stay on. Also disconnected the cable from it and relied on the manual parking brake. That was after replacing the brake shoes in the drive line brake.

Just wondering, did you just pick up this RV today? You gotto have those 2 switches. The grey switch is just above the actuator and the green switch is just above the reservoir (tank).

parking brake
IF you have the early version of autopark, and IF that is an actuator spring canister you see on the passenger side frame rail, you should be able to physically trace the hydraulic line from the canister towards the front of the coach. Somewhere along that line you should find a pressure switch. That switch is sposed to turn on the parking brake lite on the dash if the system pressure (from the power steering pump which has gone thru the fancy Bendix valve under the coach) whenever the system pressure drops below about 60 psi.
If you need more info, I can be reached at rhaag11@charter.net.
