Passenger side break light and turn signal don't work. I replaced the fuse and all the Bulbs and it still doesn't work. Don't really know what to do after that.

Check for grounding. Turn the lights on and if you have a voltmeter, make sure you have a ground and read the voltage coming into the bulb socket. If you have electricity there, there may be a ground fault. If you don't get a reading at the bulb, go back to the next connection and check for connections and voltage, Keep working back until the fuse box. Broken wire? No good ground? Corrosion in the bulb socket? A shot of WD-40 may help and a very stiff toothbrush to clean it. Do you have a trai9ler package? I have found the connector to the trailer has caused some issues. If you can, disconnect it, ans see if you lights on the SUV works.
