Brake lights/turn signals

The car was recently in a accident. It was hit in the passenger rear fender. The tail lights were not broke. The rear running lights still work but the brake lights and turn signals dont. Also the hazard lights dont work. How ever the third brake light in the rear window does still work. Do you have any suggestions on what to check next and where is the hazard flasher located? I have checked all the bulbs and they are all good. When I turn on either turn signal none of them blink nor do any of them light up that includes the front ones, the rear ones and the indicators on the dash. I will check for damaged wires and get back with what I find. Thankyou.
