I have a similar issue.
1999 toyota tacoma truck 2.4 liter engine
Problem: both power outlets (things shaped like a cigarette lighter) do not work
The cigarette lighter does work
I caused the problem by running a power inverter (thing that converts dc into ac power) to power a air compressor to pump up air mattress while camping.
I checked both fuse boxes (the one side the cab and the one under the hood) and none are blown; I could not check the fuses/relays that were not see through such as: head, heater, tail, st, efi, and power outlet.
Could it be the Power outlet relay???? In the pic labeled "HPIM1527" i pulled out the "power outlet relay and laid it sideways so that you could see it
