Default Need a wiring diagram for a 74 Nova

For about a year now my buddy's nova has had problems with the lights. The biggest issue right now is that the driver's side front blinker won't blink, it just stays on, and the rear does nothing at all. The rear one also doesn't light up when you hit the brakes. I've changed the bulb, the fuses, the bulb socket, and even traced the harness from the steering column to the trunk and there are no breaks in any of the wires. I'm at a loss, so now I have to check the diagram (that I can't find anywhere online) to see what I might have missed so I can finally put this problem to bed.

You either have a problem in the directional switch itself or a damaged wire which is not visible just by looking at the wire.

Alright, I'll check for anywhere the wire might've gotten pinched or pulled to see if I can find the bad spot.

I assume you've cleaned the sockets, could be at least on the rear the spring in the socket is worn out, dos the tail light work?

Do the hazard lights work? I am not a 100% sure your nova has a single flasher for both turn signals, and hazard, something to check, may have two flashers.
