When you say NO power to right headlight is that LOW, HIGH, and FOG, or Just one of them? Lets say it is only the Low beam and the others work. Check with your meter at the fuse for the right low beam. If you have power there but not at the plug for the headlight then probably the Lamp Failure Module is the problem. If you don't have anything at the fuse but the left side works than you have some kind of wiring problem. In other words, we need to know exactly what works and what doesn't. Then I think we can help.
