Brake lights not working-turn signals acting weird-Help!

I have a 2005 Jeep Wrangler TJ. All of a sudden, both turn signals started acting weird. When I turn on the turn signals, the front lights work but they flash quickly. The front signals flash on both sides. They do not flash on the rear lights. My tail lights work on both sides, but both brake lights do not work. I checked the fuses and they're good. Are both of my rear brake lights burned out or is it something else? Thanks for the help in advance!

This is caused by one bulb being bad. Look for bulb that is bad that is causing the fast blink. This is caused by change in impedance of blinker circuit. Automation engineer, and have experienced same issue before. Probably both rear bulbs are bad in your case. But if both went bad at same time its unlikely, could be broke wire also which would also change impedance. Check bulbs first then see where you are losing your voltage or ground..
