I replaced the lighter in my truck a while back. It's been working fine until a few days ago. It won't get hot or run a fan. I checked it with my tester and the hot is getting fire but the inside wall where it grounds seems to bee the problem. When I went to check it, I stuck the probe in there and it was magnetized.

And not working as a ground.
What could be causing this? Could the hot be shorting and cause it to become magnetized?
I'd appreciate some kind of advice as to where to start looking.
