Question about 2003 Ford Crown Victoria
Tail lights don't work but break lights do. marker/parking lights don't work but turn signals do work, front and back. noticed this as i was leaving work and when i got home i could not duplicate the issue, nor could i fix the issue when i first noticed it, at work.
Duplicate the issue ? You mean the lights are working now ?
The turn signals and brake light circuit is one and the same. The parking lights are on a different circuit. The parking lights get power from the headlight switch and don't travel thru the turn signal switch.
So have you checked the park fuse for power ?
The location of the fuse should be in your owners manual.

The ford explorer sport track. Will have a short either at the plug of the multi-function switch or 6 inches down where the column bends the wires during tilt.

Sounds like the multifunction switch. Try working the hazard switch up and down a few times to see if you get some lights to work. If so then replace the switch.

Tips for a great answer:
G100 provides ground for the right front turn signal lamp
G302 provides ground for the left and right rear turn signal lamps

The marker lamps
The tail lamps
The license lamp
The front marker lamps are grounded through the turn filament of the respective front park/turn lamp. The front marker lamps light as a result.
The automatic lamp control function turns on the park lamps and the headlamps. This action occurs when the ambient light sensor determines that the exterior lamps should be turned ON based on the amount of available light. When the BCM grounds the park lamp relay, voltage is supplied directly to the park lamps, bypassing the turn/headlamp switch assembly. When this action occurs, the following conditions exist:
The automatic lamp control relay is grounded.
The headlamps turn ON. Refer to Headlights/Daytime Running Lights (DRL) Circuit Description .
The lamps turn OFF when the BCM does not ground the park lamp relay or the automatic lamp control relay. This action is caused by the following conditions:
The available light reaches a predetermined level.
The ignition switch is turned to the OFF position
