Where is the backup light switch on a jeep Grand Cherokee?

The backup light switch on a Jeep Grand Cherokee is typically integrated into the transmission. It's not a separate switch you can easily access like a headlight switch. It's a mechanical switch activated by the position of the transmission shifter. Therefore, there's no single location to point to as a "backup light switch". Troubleshooting usually involves checking the transmission's linkage and the wiring to the lights themselves.
