1999 Dodge Ram Headlights not working correctly

My dilemma is that my headlights are on brights and they not shut off unless I turn the lights off altogether. The drivers side dim does come on but yet the other does not, when you try to turn the dims on. My dash indicator light just goes dimmer and does not ever shut off either. My drivers side taillight works fine til I hit the brakes and then it goes really dim when the running lights are but works fine when they are off. I have replaced the multi function switch and the quad beam relay. The grounds seem to be in good shape.
