Default No brake lights passenger side only

I have a 96 318ti. When i brake, only the lights on the driver side of the car lights up. This includes the front turn signal and the rear. However, the lights on the passenger side do not light up.

Passenger side Front Signal - No voltage to any of the wires when the brake is engaged.

Passenger rear lights (see attached picture) - voltage appears on both wires A and B, when the brake is engaged. However, the mainboard that houses the light bulbs do not show voltage to any of the bulbs.

** the rear lights on the driver side... only one of the wires (B i think) has voltage whent he brake is engaged, unlike on the passenger side where 2 of the wires has voltage.

*** I've tried swapping light bulbs from each side. It does not make a difference.
