Bad or misaligned stop light switch
Are you certain the transmission is in Park? Something similar happened to me. The brake light switch went out and that caused the shifter to not function properly. Check to see if your brake lights work.
the brake lights are on a separate cuircut,if your brake lights are staying then it will be a fault with the brake light switch. the switch is located under dash,and will be on or very close to brake pedal.
The same thing happened to me. It's the brake lights switch either under or over the brake pedal. The same thing happened to me. It's the brake lights switch either under or over the brake pedal.
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.
Probably a brake light switch.
brake switch ???
The brake lights on a 96 Jimmy are operated by the brake light switch, mounted on the brake pedal assembly. If the switch is bad the lights could stay on or off, or be sporadic.
Brake Lights "Stuck" ONUsually that is caused by the brake light switch becoming "out of adjustment," but sometimes it can be caused by a defective brake light switch.
There is a switch just above the brake pedal that is called the brake stoplight switch. When the brake pedal is released, it stops the brake lights from illuminating. Check to make sure the switch is contacting the brake pedal stop where it should. A short term method of not killing the battery would be to unplug the connector to the switch and get a new one. It won't have brake lights when disconnected so I don't recommend driving with it like that. replace the broken switch
If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.
Those tail lights could be the brake lights you are seeing and that would be a faulty brake light switch or the brake light switch is out of adjustment.
fuse, bulbs
