I have a 2001 4Runner. The 1999 might be the same.

Under the hood, behind the battery, is a black fuse and relay box. The
power outlets have a relay there, and it's marked on the cover which one
it is (right rear).

On my vehicle I removed the relay and jumpered the connection so the
accessory power outlets are always on, as shown in this picture:

You can make a jumper out of two male spade lugs and a piece of wire
(use a sufficiently high gauge of wire). At least you can use it to see
if it's the relay that's bad or something else (fuse) is blown. If that
wire gets the outlets working then you can consider getting a relay if
you want the outlets switched on and off with the ignition. You could
also check that the relay is getting power to the coil connections using
a multimeter (two of the three top pins in the picture must be the coil
voltage.

I think that the fuse that goes to the power outlets, is the 15 Amp
"ACC" fuse inside the car, (top row, middle column), and that it's
between the relay and the outlets, so if the relay is bad the fuse could
be good and the outlets would have no power. Check the fuse first. If
the fuse is okay try jumpering the contacts as shown in the picture.
