Brake lights not working
The multifunction switch is probably the answer, have you lost any other switches on the car. Also check the fuses. The best thing to do is purchase a new one from ebay. it will save you money, are you planning on installing it yourself?
have you lost your turn signals on the front and what about your high beams. if all the front lights still work by the switch, then its probably not the switch at fault.
If I adjust the turn signal and put the pressure in the direction to the steering wheel the signals and brakes work fine. I'm thinking something is loose in the signalling arm.
