Cig lighter died, please help???

Hi, I have a 91 Ext Cab 4x4. The other day, my cigarette lighter quit working. I checked all the fuses that I could find, and none were blown.

Is there a hidden cig lighter fuse? I havent had the time to test the wires yet, but could it be the receptical itsef?

I was using it to power a power inverter for my laptop. It has been used everyday for almost a year.

Is there anything else that I should check????

Thanks.
