My brake lights only work if parking or brake lights are on. The relay clicks in all cases if pedal depressed?! Bad relay?

If poor grounding why do they only work if lights are on?Check your grounds.
There has got to be another source of power you are missing. keep digging.Lights flashers directionals all work as they should with out the lights on but - brake lights only work if the parking or headlights are on. The brake light relay clicks as it should also!
