Question
I have a 95 buick lesabre. Left brake light doesnt' work...but turn signal and hazzard light on left does. Where is junction box/switch that feeds the yellow wire on left side the current for the brake light?

Answer
..the brake lights don't go thru the flasher, or they would blink when applied.
But they do go thru the turn signal switch, which could have a bad contact.
The emergency flashers may also use the same bulb, and therefore, a bad contact in that switch is also a possibility.
The block where the wires pass through the firewall is another place where a loose connection can exist.
double check the wire on the brake switch above the brake pedal.
