Right front went out, I tested by removing and putting on left side, it works fine. Put working Left side into right, it does not work. Used the bulb and saddle and tried combinations but right side will not work. ALL other turn signal lights work. I am not positive where to look as the conductors and wire seem fine and I think I need to remove the entire headlight assembly to get a meter on the contacts. But I figured asking first is a good idea.

Yes remove the headlight and check the wires. Check the hazard lights to make sure it doesn't blink when that switch is turned on first. Ive seen the hazards work and the turn signals not before due to a bad flasher

Result: Turned on flasher, right side bulb did not work. Since I had removed it before thought I'd better make sure it was 'twisted' in to contact position so I rotated it and it started working. Turned off flashers and turned right turn signal on, it works. My thought is the internal connection might be bad? (The conductor ring inside the housing) Do you replace that with and entire light housing assembly? Or am I completely off base? Great car, never had any issues except this.
