Re: 1993 Nissan 300zx Brake lights don't work
I had the same issue with my 1990 300zx Coupe and resolved it by replacing the tail and stop lamp light sensor.
This is the name Nissan uses to refer to the part.
While searching the web, I found the part also referenced as a Brake Lamp Module.
NOTE: Dont listen to auto parts store employees that dont use the internet. I spoke to a local parts dealer and he felt that since he had never heard of it, that it didn't exist. The bad part number was 28426-30P00, which is no loger available and was replaced with 28426-30P01 which worked fine. Here you will find an excellent resources showing the location of the part, the part number, and sites where you can buy the part.

Hi Lori,love 300zx's,got a 85 Nissan 720 4x4,Here's a link to the stoplight switch,directs current to the brake lights,could be bad.It is connected to the brake pedal,get a flashlight and a adjustable wrench and remove nut and electrical connector,when installing,make sure it is adjusted correctly.
Push the driver's seat as far back as possible, allowing you to lay on the floor on the driver's side.
Shine a flashlight at the top of
the brake pedal stalk and find the stoplight switch. It will be a
plastic cube either connected to the brake stalk or directly opposite
the brake stalk, depending on the vehicle.
Depress the brake pedal and feel
where the brake light switch contacts the stopping plate, a metal plate
in direct line with the stoplight switch.
Feel for an open hole where the
stoplight's plunger-style button presses. If a hole is present, you
simply need to replace the rubber stopper.
Press and release the
plunger-style button on the brake light switch and ask an assistant if
the brake lights are turning off and on. If not, the switch is bad and
must be replaced.
Stoplight Switch Stopper Replacement
Clean out any remaining debris left behind by the old stopper from the hole that the stopper goes into.
Press the new stopper into the hole on the metal plate until it snaps into place.
Shine the flashlight on the stopper and check that it sits flush against the metal plate.
Press and release the brake pedal and ask your assistant if the brake lights are turning off and on.
Replace the stoplight switch if the lights continue to stay on.
Stoplight Switch Replacement
Loosen and remove the bolts
holding the stoplight switch in place. It could be between one and four
bolts depending on the vehicle.
Pull the stoplight switch from
its mount. Disconnect the wiring harness from the stoplight switch by
pressing or pulling the locking tab and puling the harness away from the
Plug the wiring harness into the new switch until the locking tab clicks into place.
Place the new switch on the mount the old switch was removed from and tighten the bolts with a ratchet and socket.
Press and release the brake pedal several times and have your assistant check for proper operation.
Check to see if your brake lights are working. Chances are the brake pedal switch could be bad. Also there is a solenoid in the center console that is activated by the brake pedal switch. Either one of them can cause the problem. I do not know the cost as a dealer would charge you at least $75.00 plus parts to fix it. A regular repair shop may charge less depending on the actual time it took to troubleshoot and replace parts.
The hole in the pedal arm is for the cruise control. There is a plastic plug that needs to be in place to turn off the brake lights. They should be available at any dealer - there is also one for the clutch pedal arm in manual trans. These are required for the cruise as well as to turn off the brake lights. I bet that several will now be able to have their cruise back.
