Did you use a DVOM - digital volt ohm meter an test for B+ voltage to the brake light switch ? Who cares if the fuse looks good , if there is No battery + voltage on either side of the fuse it's not going to work . Looking at a wiring diagram to know which wires to check an using a volt meter to test is the proper way to diagnose .

SOURCE: Left rear brake light stopped working but bulb and fuses are OK.
take the bulb back out have someone sit in car apply brake get your self a circuit tester and check to see if this circuit is carrying efficient 12 volt current! some times in cold weather these bulbs get hot with long period of breaking and when released condensate and rust begins and you get what you have perhaps bad socket! this would be a ideal location to begin and probably end,

These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!
