Brake Fuse keeps blowing
It blows once I step on the brakes. However, the brake lights still light up when I pull the headlight switch. If it matters, the chime sound you get from the headlight **** being pulled is not there anymore either I'm not sure if it's related to the fuse. Thanks

You failed to mention the year and model of your ThirdGen therefore some details to this diagnosis have been omitted.
OK we assume you’re talking about real bulbs and not just LEDs.
First check all bulbs to make sure they are the correct type, and installed correctly.
A common mistake is people installing 2 filament bulbs 180° rotated.
Some crazy symptoms have been reported doing that.
Disconnect the connector near the left rear which goes to the taillight assembly.
Does the fuse still blow?
If yes, the short is located between the brake-light’s switch light blue wire
and the left rear connector.
If no, the problem is located in the taillight assembly/harness.
With the connector still disconnected, use a 12 volt source, with a fuse in series with the probe, to apply power to the light blue wire at the taillight assembly’s connector.
If the probe’s fuse blows, you can remove bulbs to see if they are the problem.
If the probe’s fuse still blows, the short is in the harnesses’ light blue wire.
Now trace the light blue wire until you come across what it is shorting to.
