This can be cause by 3 things. The most common being a blown fuse. If this is not the case, I would check the bulbs. If the bulbs are fine, then you might have a wiring problem. The easiest way to diagnose this, is to turn your lights on and use a multimeter to see if you're getting power to the tail light unit. The flow of power should not jump around, it should be a steady flow of power between 6 to 12 volts. If there's no power going to the unit, then you need to trace down the wiring that runs to them, you should also check to see if anything else has stopped working properly, such as turn signals and emergency flashers.
change the brake lights check the fuse check the brake light swtch
Check the bulbs, the fuse and the brake light switch.
Blown fuse? Bad stoplight switch? Open wire to brake lights Not ground at brake light sockets? Problem in steering column (turn signal circuitry)?
where location of brake light switch on 1989 chev, truck.
It plugs into the taillight.
Check bulbs, fuse, bad ground, brake light switch.
adgust the brake light switch at the brake pedel under the dash
Please re-phrase your question; it appears you are saying the brake lights come on when you push the brake pedal and the lights are working (normal operation). If the lights are staying on after you release the pedal, then the problem is with th brake light switch (sticking). Thanks Malcolm
You left some wires unplugged.
On a 1989 Acura Integra hatch back the brake lights are reached through the hatch itself. The brake lights housing are on the rear of the vehicle. Unplug the bulbs and replace them.
yes
It may be wired wrong.
