Problem with park lights and the tail lights not working

The dash lights are on the same power circuit as the tail lights for safety reasons so you will know when the tail lights go out. If you have now lost just the tail lights, I would expect you have a wiring problem going to the lights. Could be front or rear. this guide can help us fix it

let us know

You just need to follow a wiring diagram systematically until yo find the issue.
You have a Lighting Control Module under the dash on the drivers side that actually controls everything. If you have a short circuit in the tail light wiring, it could have burned out the module now.

That is for you to determine through testing. There is no magic answer I can give you without testing anything. Someone that know something about electrical testing and circuits needs to do this. I have given you the necessary diagrams.

All the colors are right in the diagram.
The wire leaving the module, going to the rear lights is BN (brown). I would probably start at that point to determine if the issue is after the module or not. Again, if you are not familiar with electrical circuits and testing you can do more damage than good so I suggest you let the electrical expert do this.
