Question about Jeep Cherokee
Check to make sure you have power going into the fises.
The two fuses (7 and 23) both do not receive power until the switch is turned on.
I would be relatively certain you will find no power and are looking at a new headlight switch.
The grounds are shared with the brake lights, and you said all other lights work, so you know your grounds are good.
The only thing you have in common with all failed items (tail and tag lights) are wire and the headlight switch.
Failing a bad switch, you will have a wiring issue, it is far less likely though.
When you verify the fuses are good but not powered, you can verify the integrity of the rest of the system by applying power to both of those fuses externally. Your tail and tag lights will illuminate.
If you have any questions or request details of the wiring system, please let me know and I can clarify for you.
