Answer


brake light or lights out. all 80's n newer cars have this let me know if it is it

- vacuum check valve (under ignition on driver side)
- vaccum tank (in front of front driver side wheel)
- vacuum hose (all, including the one going to the vacuum release valve on the brake pedal)

- vacuum release valve on the brake pedal
- electrical switch on the brake pedal
- turn signal lever (cruise control)
- cruise control servo
- cruise control module (part of the digital dash), in particular the transistors driving the vacuum valves in the servo


Made a detailed article here. It is in french, post a personal message in the forum if you need help with translation or anything else. I had 3 issues in my cruise and cured them all including digital cluster problem.

If the cruise control on your 1987 300ZX does not work, you might have an issue with the cruise control fuse or wiring. You could also have a problem with the switch that turns the cruise control on and off.

First step might be checking the vacuum lines in the engine bay. If the cruise control unit does not get vacuum it will not work. Second, the brake light switch might be suspect at that age, it might be sticking or not working. Last, the buttons inside the car or the cruise control unit might have failed.

My front left (driver's side) brakes caught on fire and my cruise control hasn't worked since. You might want to check the connection from the cruise control to the brakes....

The most probable cause for your malfunctioning cruise control is a blown fuse. The fuse might have blown while you were changing your switch. The cruise control fuse can be found in the fuse box.

If the cruise control will not engage, there might be a problem with the Electronic Fuel Injector or the MAP Sensor. There might also be a problem with the Oxygen Sensor. Some autos have more than one oxygen sensor.
