Definitely sounds like a short somewhere. Is the issue only with ONE taillight (meaning left, or right, or one on the tailgate) or is the issue with all of the taillights?

Are there any more warning lights on the dash at this point? what's the current state of the car?

when i cut that converter off the turn signals works fine and it wos fine. but taillight still doesn't work. and when i start the car it is fine, but when i push brake pedal the light that shoes that one or more bulb doesn't work on desh bord comes on. even if the light doesn't turn on.

yes it is all taillight gone on the gate and on the car. and car located in washington state.
