wierd turn signal problem!!

hey guys ,see if u electrical gurus can help with this. so i replaced my turn signal cam..before doing so all my lights worked fine just the little clips that hold the cam in the left or right position had broken. Now that I replaced it when i have my headlights on the off position my left brake light is brighter then the right side also both my signals work..but when i turn my headlights on and hit the brakes only my right side brake light gets brighter,and when i put my left signal it doesnt work only upfront. i have checked all the grounds and cleaned them up no signs of rust or rott also i replaced all the bulbs and flashers. hope someone has an answer or can point me in the right direction:cheers:
