All brake lamps are dead.
and fuses are good. (did you check the right ones, or all?)
what about 3rd lamp?
if they look blown they are, why question that for $1 lamp.
replace lamps that are blown, the filament goes byebye.
fuse #9 is STOP, replace this on suspission
fuse that look ok, can have hair line cracks, we test them with a meter. so as not to guess...
next is this power 12vdc from stop fuse goes to the
stop switch and if stopping (foot brake) the output goes to 12vdc and all lamps on rear (stop)glow.
its cave man simple (unlike new cars that computers do all that)
now my advice, replace all 3 lamps
or take them out 1 by 1 and try them 1 by 1.
because lamps can SHORT and blow that fuse.
all there can be hand for $3,... and a new fuse for 50 cents.

One of two things cause this corroded or poor chassis earth at the bulb holders or the circuit board that holds the bulb is faulty.

have you checked the earthing continuity-if it's this other bulbs may also partly light when brakes used
otherwise-
Check continuity of live from center to lh & rh lights and/or is there a live at those lights

Apparently this is a recall matter and will be fixed at no charge. KIA Consumer Assistance Center 1-800-333-4542. Recall notices were to go out in May/June 2009.

I had a similar problem with my 1994 S-10 LS extended cab. Both tail brake lights worked fine. I removed the 3rd brake light cover and tested for voltage at the steel center of the two rivets and found the positive (driver side) negative (passenger side) were good. I checked the two metal strips that send power to bulbs and found the positive side was open. Seems the flared side of the rivet was not making contact with the metal strip. I bucked the rivet with a punch and hammer and it took care of the problem.

I had the same problem and found out that both light bulb sockets had corroded/burned contacts. After cleaning and applying dielectric grease, they worked perfect again.
