Brake Light Problem

[NRogge]

When I press my brake pedal, only the far right brake light lights up pretty damn bright. All of the others do not light up. When my lights are on, the far right brake light is lit, and the others are also, but they are dimmer than the far right brake light. I switched all of the bulbs and it still does the same thing. I hear a relay click in the engine bay but im not sure which it is. Also, when I press the brake the light on the sliding knob that controls the cold-heat on the air flashes and the clock light also flashes( only if my lights are off)

if anyone could point me in any direction before I start to diagnosis this tomorrow that would be great. thank you

One or more of the grounds on the tail light sockets are bad. Very common on the coupes, occasional on fastbacks. '93-'94 Altimas are notorious for it too.
