The front yellow lights and rear brake lights stay on even when the car is turned off. I removed all the fuses I could find for the lights located under the rear driver side seat and the rear left light still stays on.

What should I do to help diagnose and resolve this issue? I think it may be the brake light switch but researching online but I'm not really educated in automotive repairs.

To further elaborate, I took the brake switch off and they stayed on so I'm starting to wonder if it's some timer that's supposed to shut the lights off after a certain amount of time.

Hello,

It sounds like the turn signal flasher module is not working right. here is the location as you can replace it. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
