Left turn signal mystery

[Hydra]

When I got my truck the wires to socket were cut at the very base so I got a new socket and I have it wired up but when I turn on the park lights or the turn signal it won't turn on? It's getting power at the socket and I've put in 2 different bulbs and it still won't come on.when I hit the lever for the left turn the dash indicator is just a steady green but won't flash if that helps.also the blue wire is acting as a ground when I have the park lights on and I haven't tried it with the signals,is that of any importance?
