Possibly the brake light switch. not sure where it is located tho. maybe under the dash attached to the brake pedal lever. it may have a spring loaded button on it so that as soon as you push the brake lever the least bit the button comes out allowing the switch inside to connect. this switch malfunction usually causes the brake lights to stay ON tho.hope this is the problem.
Have you considered the relay? I believe the brake lights are engaged via relay on the 2000 Blazer. Check your hazard lights and your third brake light.
I am the previous anonymous. I have done some research and discovered that your vehicle has actually been recalled because of this very problem! Check the NHTSA's website or contact your local Chevrolet service center to set up an appointment for free service on the recalled part (actually a multifunction switch which also relates to your hazard lamps). The recall Campaign ID is 01V364000. The Part Number is 506377. .
check your hazard switch. despite what most dealerships say, you can replace just the hazard/4-way switch which is much, much cheaper than the entire turn signal assembly they try to sell you. that fixed my brake light problem
brake lights are wired through the turn signal switch. the switch is needed to interrupt power to the brake light that needs to blink for turn signal useage., also to allow the lights to blink when flashers are used.
turn signal switch failure is usually the cause of no brake lights. replace the switch assembly. if the third brake light always works then it is the turn sig switch assembly that is causing the issue with the brake lights not working.
It is important to have working brake lights on a vehicle. If the brake lights are not working a person should first check the fuse, bulbs and at last the wiring.
i have tail lights but do not have brake lights nor do i have turn signals. i have replaced brake switch and all bulbs
Working brake lights are important for safety reasons while driving. It is important to check all of the wiring, if the brake lights are not working and the fuses and bulbs have been checked.
Check sockets and grounds
Check the brake light switch.
Check the fuse, check the bulbs and check the brake light switch, it should be one of those.
Check the fuse, check the bulbs and check the brake light switch, in that order.
use BMW bulbs and parts
AnswerThe bulbs for the brake lights are usually separate from the normal tail light bulbs. Check and replace the brake bulbs first, and if they are still not working examine the fuses, switch and wiring.
How about a malfunctioning brake light switch
on some cars the tail lights and brake lights are totally different bulbs gain access to the bulbs and have someone push the brakes so that you can determine which bulbs are the brake lights and replace the tail lights
I assume you have checked/replaced the bulbs. Take a cicuit tester and check the wire harness connections under the bumper and around the trailer connector if you have one. The problem must be at that area IF all your other lights are working as you said.
I hate to ask , but did you check the bulbs ? The tail light portion may work fine , but the brake lights don't if both of the bulbs are bad .
mines dun this it was wen a replaced the rear brake lights it was dogy bulbs put new wans in n it was sorted
Check the switch at the brake pedal .
Check the bulbs,if not the bulbs you most likely have a bad ground.
I just had my Daewoo Leganza brake light switch replaced. It goes under the brake pedal. and now my brake lights work fine.
its on different bulbs
Check fuse, check bulbs, check brake light switch, check wiring and then check signal switch, in that order.
check wire continuity- no power no lights
check the wires at brake light switch on brake pedal they are bad about breaking brake light switch
Likely to be the brake light switch on the pedal at fault if the bulbs and fuses are good and other lights work ok.
Check the bulbs they are double filamented -smaller for brake lights larger for tailights Check the fuse Check the stop light switch usually located at the upper end of the brake pedal under dash area
Check the fuse first, then the brake bulbs. When you press the brake, it senses the brake lights and let's you take it out of park. This happened to me - 2 brake lights burnt at the same time with one already gone, and I couldn't get it in gear. I replaced the bulbs, touched the brake pedal and she went into gear no problem.
There might be a separate fuse for the lower brake lights ( just a guess )
