I have a 2006 Dodge Ram 2500HD 5.7L. The Left side head light, tail light and both front and rear turn signals work. The Right side head light and both front and rear turn signals work however if the turn signal isn't on the right side front amber marker and rear tail light don't work. All the bulbs are fine so what could possibly be the problem?

 

could be the same as im experiencing with the circuit board geeking out...my lamp out comes on and off for a cpl days now and my bulbs are fine...im gonna have to replace the things...rockauto has em for 30 bucks shipped....
