What would make the Dash lights blink when the turn signal is turned on?

The headlight wire in the turn signal switch wore into and caused the headlights to quit working. We changed the signal switch out, but after changing the switch out we have no daytime running lights, no left turn signal sometimes, and when u turn the head lights on; u have no left turn signal. When u turn the lights off and turn the left signal on both the left and right blink. The right signal blinks fine when u turn it on. Also when u turn the hazzard lights on the dash lights flash along with the radio lights. They also blink sometimes ben u turn the left signal on. Can u please help me diagnose this problem?

Thanks brad mcmillan
