You have probably figured this out by now, but I have had the same problem, and in case someone else also has this problem, this is how I got my lights to work again.
First, my turning signals and brake lights stopped working after I tried to turn on the hazard lights. Come to find out they are all weirdly connected and pushing the hazard light messed everything else up. As Joe said, the switch is in the steering wheel. In order to get things back to normal, we had to push the hazard button, then flip the turning signal. We repeated this process multiple times until we saw the turning signal work! Then stop pressing the hazard button and never press it again, or it might trip it up again!
Hope that helps!
