Turn Signals not working...possible relay??

Hi there...I installed a new radio that is under the dash (in between the ash tray and glove box) in my 72 duster. When I recconnected my battery terminal, the radio worked completely fine, however, the turn signals do not work. They do not light up on the dash or work on the exterior of the car; however, my hazards work just fine. Do you all think I could have just tripped the relay while working underneath the dash? If so, is it just a matter of pressing in the relay to fix it or what? Any help is appreciated. Thanks mopar fam!
