Why do your hazards come on when trying to use your directionals in your infiniti?
Sounds like there is a problem with the turn signal switch but it could be another problem. First you need to see if the hazard light's work normally when turn signal is not on, if it does the the turn signal switch is the problem. If your hazard lights do not function when you turn the hazard light switch on, then it's a simple fuse or flasher canister that has gone bad and your hazard flasher is in the on position. If the Hazard light's have a bad fuse or flasher canister and is in the "ON" position it can cause the problem you describe.

How do you repair brake light short headlights on no brake lights just the cyclops lights off brake lights and cyclops all bulbs new and correct no obvious wire damage or switch wear?
Your question was a little unclear, does the brakelight work when the headlights are off but not when they're on? If that's the case, it's a ground problem. Check the ground to the tail light/brake light assembly. If the brake lights don't work at all, check the turn signal switch. Brake lights are routed throug the turn signal so that you can use the same bulb for turn signal and brake light. BTW, if you have an air bag, don't attempt to replace or inspect the turn signal switch yourself. It can be very dangerous.
