1987 Caprice Station Wagon, right turn signal won't come on and dim right side headlights

The bumper light is very dim and seems to have a bad socket but the head lights are also dim on the right side. The turn signal indicator on the dash is faintly lit. But every thing works fine if you use the emergency flashers. Help I need to drive this at night and I can't because of the one bright head light and one dim head light and no right hand turn flashers either front or back. I am leaning towards a short to ground but the car is in mint condition. I was trying to find a wiring diagram so I could trace wires. Thanks if you can help
