30 amp circuit breaker melted. Looks like there is a short, power door locks,trunk release or front seats? where do I start?

 

Hi, maybe its helpful to get som trouble codes, turn on the ignition but don`t start engine, then pull the off and the warmer button of th A/C at the same time for a few moments, on the displays are now shown the trouble codes of your car. To get off pull the defog button. Notify your trouble code and post it here, maybe any one can help you more.

 

disconnet the seat and trunk locks and see if you still have a short if it gose away at this piont its your seat or trunk locks.
