Hello I'm new to this. Have a problem with break lights not working after rain got in bulb unit . Changed bulbs fuses and whole rear light unit and still not working. checked earth connection that's fine not loose or rusty. I'm thinking it's the break light switch under the peddle or a loom problem. Can any one shine some light on this problem please as I'm left with one grumpy misses that can't drive the car not good.
