It is the brake light switch. The 3rd light has a different switch. GoodluckJoe
you can check under neith the bed for fire where they come together. if ther is fire it is the circuit board where your lights go. if there is no fire then its gonna be in the turn signal switch
Depending on the year, there may be one fuse for all three brake lights, or two fuses, one for the highmount brake light and one fuse for the two lower brake lights/tail lights. So, if all three brake lights are out, it could be just one fuse or perhaps the brake light switch which is on the brake pedal metal arm assembly.
Check the brake light bulbs, Check the brake light fuse, Check the brake light switch, In that order.
the brake light driver side not working
The brake lights in your 1983 Nissan pickup truck are controlled by the brake light relay switch. When the brake light relay switch malfunctions the brake lights will stop working.
probably the brake light switch on the pedal if none are working at all
There should be a fuse for the brake lights. If the fuse is good always check the ground wire.
Bulbs blown, or corroded sockets.
If you brake lights are not working on your trailblazer it could be due to a number of reasons. Your fuse could be blown, or your light may no longer work.

if turn signals are working , and brake lights not working, i would replace the stop light switch on the brake pedal

Check bulbs, fuse, brake light sensors.
