I just bought an 83 Camaro about 2 months ago and recently I started having troubles with some of the electrical system in the interior.
When I first bought the car, the left turn signal worked for a little bit, then it stopped but for some reason when I pulled the headlight **** out and bumped it, the left turn signal came on again and since then, has stayed.
Also the interior light, which on my car comes one when you turn the headlight **** all the way to the left, had the same issue. If you played with the **** a little, it would work, but now it doesn't work at all, even though the bulb hasn't burnt out. And about the same time that happened, my radio quit working as well. It comes on and I can hear sound out of each speaker, but no it's not picking up a signal at all even though everything is connected right.

I haven't found any blown fuses yet, so I'm assuming its loose wires. My question is, are any of these problems related?
