What could cause one brake light to work but not the other, aside from the fuse under the dash? the bulb works if we put it on the other side. good bulbs do not work in that spot. the cap the bulb goes into has also been changed, so its not that. we also changed the fuses under the dash. anyone have any ideas?
Wiring issue . Do you know what a wiring diagram is ,what a DVOM - digital volt ohm meter ? How to trouble shoot automotive electrical circuit's ? How about voltage drop testing. If one brake light works the fuse is not the problem , one fuse powers both. It would be best to look at a wiring diagram so you know which wire at the brake light has the B+ voltage an test at the bulb Doing voltage drop testing .

Is it a power feed or ground problem ?

Click the search button then the second blue link . Scroll down to the third diagram , on the right side of the diagram , notice fuse #13 20 amp. under that the brake lamp switch .Then notice BS01 - this is a body splice , good spot for trouble . Then do you see the white with tan trace wire ? this supply's the B+ voltage to the brake light's . Could have corrosion in the wire's inside the tail lamp assembly .
Get a test light and check for power. If you got power check the ground, and the contacts, if not follow the hot wire back to the brake switch to locate the short.

Do you own a test light? Check for power at wires behind socket? Clean socket good , check contact spots for bulb & clean any rusty side of the socket with emery cloth, or sandpaper, for good contact also.

i have the same problem you have to put a bit of solder on all the tips of the connectors were the bulb goes in and it will be fixed

You may have used the wrong replacement bulb, check that

Your owners manual should tell you, but look under drivers side dash as well, for a black panel that you undo , and drop down to expose another fuse panel.
