Park, Sidemarker, Tail and License Lamps
Voltage is applied continuously to the PARK fuse to the headlamp and the instrument panel (IP) lamp dimmer switch through CKT 1340.
When the headlamp and the (IP) lamp dimmer switch is in the PARK or HEAD position, voltage is applied to CKT 9 thus activating the following lamps:
• The park lamps
• The side marker lamps
• The tail lamps
• The license lamps
The park/turn lamps are the only lamps that do not activate yet receive a current from CKT 9. The park/turn lamps do not activate because the voltage drop across the front side marker lamps is much higher than that across the turn lamp filaments

SOURCE: 1998 wrangler turn signal/brake light short
your socket may not be grounded properly, I have seen this before, and the simplest way to fix is change the socket with a new one.Not another used one it may also be bad.
SOURCE: 1996 carpice classic park lights fail
their is another fuse box in the engine compartment check that as well
SOURCE: Taillights are not working
check for voltage in the socket. positive is the center connection. if you have no voltage there, then you may be right. Make sure that you check the wires.
SOURCE: No Brake Lights, unable to switch from park to drive
It is not the multifunction switch. The power feed goes thru the brake switch before the multi function. You have no power the the brake switch because your shift interlock is not allowing you to shift it. I'll look up the wiring diagram and repost with a solution.
