Short to ground. Please help!

Hello everyone, I have a 1971 Dart I'm slowly restoring. I was attempting to restore the functions of the blinkers(new switch and flasher), when I realized I had a short to ground from the turn signal circuits. Front, rear, left, and right all short to ground. What is odd to me is that the hazard lights function as they should, head lights, dome light all function. No blown fuses aside from the radio. I disconnected the bulkhead connector, did a continuity test from ground to the pins on the firewall side. All of the wires for the blinkers are shorted out. I'm at a loss at this point, and really hoping to not have to take the whole dash apart. I'd appreciate any help at all. Thanks.
