Power outlets not working in my 99 Dodge Caravan

wrong fuse , the service manual covers all that.
aux = old cig cigar jack in cab ? <<<< names change in time
but is the same CIG port, for sure.
the manual calls it

Horn/Cigar Lighter/Power Outlet oh, so horn is dead too,, sure.
fuse 15 is front CIG
read outlet (omg 2) is fuse 6 , 50amps that feeds FUSE B
fuse B is 20 amps and feds aux rear center pin power.out.

fuse B box name is RELAY and fUSE BOX RFB.

Link below says fuse 5 or 6 under hood. From what I see I think 5

which one, ???
cig or power outlets. there are 3. of them 2 front 1 rear.
the number is
fuse 26 runs cig relay. main feed
fuse 29 runs cig relay coil.
both are in the JB, junction box.
power outlet rear is fuse 27 PDC
power outlet front is fuse 9 JB.

I'm not familiar with your truck, but, from reading up there is an aux socket in center console and then cig sockets. These are seperate circuits, centre is perm powered, cig sockets not.

When you say more than one has stopped, is it 2 x cig or 1 x cig and 1 x console?

I'd be checking the fuse and relay box under the hood, front wing sort of location (depends on year and such so I may be off here) for some circa 20 amp fuses (yellow in uk).

found this, which may or may not be the right numbers as is a different year perhaps:

Your cigarette lighter is powered by fuse #29 in the integrated power module. The power outlet is powered by #26 and if the power outlet in the center console is not working, this one is #42

Normally this would be in your owners manual.
The power for the outlets may be on the same circuit with the horn.
On some models there is an accessory relay that handles the outlets.
There should be a 20amp fuse in the box in the engine compartment that feeds the circuit. You may have to check all of the 20amp fuses to find it.

There should be a cig lighter-accessory relay in the box near the battery. It is powered by a 9amp fuse and a 20amp fuse. The 20amp fuse is in the same box with the relay.
These fuses and relay power the front and rear outlets.

You can do anything your capable of figuring out

They run off of different leads. Check fuses first then if nothing check wires then last change cig lighter outlet

All the fuses have been checked. One fuse was blown but it was the 20 amp power outlet, I believe for the outlet under the cig lighter.

fuse should be located the end of the dash drivers side
