Cigarette Lighter Receptacle Not Working

[1G_DSM]

What can cause a cigarette lighter receptacle to not work?

Mine isn't working. I don't smoke but I use it to recharge my smart phone when I'm driving. It's nice to have working especially if I'm using my GPS on my phone to drive a long distance. It's really annoying now that its not working.

One day it popped out of the socket and I had to remove the trim piece so that I could secure the darn thing back down. After that it doesn't work anymore. It only has two wire fitting connected to it.

What could have gone wrong? I tried messing with it again today for like 30 minutes with no progress.

I drive a '94 Eagle Talon. I hate these annoying little problems. It bugs the crap out of me especially since my HTC EVO 4g phone uses a lot of power.
