I have an 04 Corolla. If I plug anything into either of the 2 power outlets it destroys a breaker. I thought about replacing the power outlet, but since it happens to both outlets I think there's something else wrong.

How can I troubleshoot and fix this?

UPDATE
I found the wiring diagram for the cigarette lighter. I think the issue is at ground point IE (listed in diagram). I'm also having issues with the clock display which goes in and out. The clock appears to share the same junction point.

I was able to see the grounding points by crawling under the dash. The grounds looked visually good, the screws are tight. So, I tried replacing the 12V power outlet with a new aftermarket outlet. The issue is gone.

Strange that the one bad outlet actually caused both outlets to blow fuses when power was drawn.
