I am having the same issue with my 95 Monte Carlo... from what I've read the likely problem is the turn signal combination switch... seems to make sense to me... I thought about wiring the third brake light to the rear lights.. but that will make the turn signal not work... I'm going to have to take to a dealer
Check the stoplight switch at the upper end of the brake pedal - common problem
Check the brake light switch first. It is usually near the brake pedal under the dash. A bad turn signal switch can also cause this if the brake lights are also turn signal lights. If the brake lights are independent of the turn signals then disregard the switch problem. A good wiring diagram will help to diagnose the problem also. Check with dealership mechanics as they have access to diagrams.
Could be the brake light switch or fuse.
It has a flasher relay for the signals only.
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.
The brake relay switch is bad.
Your problem very well could be the hazard switch. i have a 1994 honda civic too i found whenever i disconnected the hazard switch from the wiring harness my turn signals brake lights and of course hazards do not work. Maybe replace the hazard switch..
i have tail lights but do not have brake lights nor do i have turn signals. i have replaced brake switch and all bulbs
The only thing common to all those lights (but not to the center brake light) is the hazard switch. I'd check that next. On my 96 Century the hazards override the signals and brake lights meaning that the signals and brake lights must be wired into the hazard switch somehow.
The turn signal switch overrides the brake light circuit while the turn signals are on. If the switch is damaged or worn out the brake lights won't work.
No brake lights but turn signals work? Turn signal switch brakes route through it.
A defective brake light switch could cause the problem. Also a defective turn signal switch could also. The brake lights work through the turn signals. It cancels the brake light so that the turn signal can work.
