Well, I noticed last night when I backed up in front of a window that I didn't have any brake lights!!! God knows how long I've been driving like this and I'm thankful I never got rear ended. I checked all my fuses and they all looked to be fine.
After doing a little research I found out that my brake light switch was done/broken/burnt. I'm righting this just in case it happens to someone and it might help them out. It's located just above the brake the pedal and it cost me $20 to fix. All you have to do is disconect the plug, give it half a turn and pull ou the switch and install the new one. It took me 2 minutes.

Hope this helps someone in the future! I sure feel safer with brake lights working now.
