i am still trying to figure out why my hazards work intermittently(sometimes only 1 side), why my turn signals went out, and brake lights went out at the same time. all bulbs and fuses are good.

after some reading, i have found that it may be my hazard switch that is causing this because i think that all these items are connected to it. Does anyone know where it is in the car, how I access it, and what i'd do to go about servicing it? thanks
