2005 Chevy Silverado headlights, fog lights and turn signa

Ok, it all started as only an intermittent problem but now it's all the time. I turned my fog lights(factory) on and noticed they were dim along with my right hand headlight. I then noticed my turn signal indicators in the dash as well as my side mirrors were faintly lit, when switched to high beams the dim indicators get brighter, right headlight is still dim. When using the left turn signal I get the left mirror indication along with the right mirror and the right headlight blinks. When using the right hand turn signal I get indication in both mirrors along with the right headlight blinking. The flashers work fine along with the turn signals as long as the headlights are off. At first this would only occur when I turned my fog lights (factory)on but now it's when ever the headlights are on. HELP!
