Brake Light Sensor Fix
This fix isn’t difficult due to the actual repair itself, but rather because of locating the correct sensor module. One of the most common causes for brake lights to stay on or not turn on at all is the Lighting Control Module located in the rear hatch compartment—either near the spare tire or attached to the right tail light assembly.
Over the years, Nissan used three different sensors, shown below:
| Image | Years |
|---|---|
| (coming soon) | 1984–1985 Black Sensor |
|
1986 only Pink Sensor |
| (coming soon) | 1987-1989 White Sensor |
✅ The fix: Simply replace your waterlogged sensor with a known good or new replacement sensor. You can get them through various parts suppliers Like Vintage Z Parts
