Chevy S-10 brake lights stay on all the time

Third brake or stop Light.

Disconnect the brake light switch and see if the lights go out. You could have a bad switch.

Check your fuses if it isn't that check and see if your bulbs are blown.

sounds to me you have a gounding problem with the lights in the back. ck the bulbs to see if they are in good shape no rust and such. than ck the wiring in the back and see if you find where they are getting the for the light at

If you have the day-time running lights, you will have to find the fuse and pull it. They make these daytime running lights because you get a 10% less chance of an accident. (supposedly)

Brake light relay is bad. It is the third solenoid from the left on top of firewall under hood. If this is bad, the third (cab top) brake will still work fine, but no rear brake lights!

There is a brake light swich along the brake peddle that need's to be adjusted. Quick and easy fix.

The abs is a add on for the brakes that when the tires come into a skid or slid they wont lock up..Your brakes will still work great with the abs disabled but your brakes will lock up if you push on the brakes hard enough to stop.Mainly abs works in slippery conditions not letting the tires lock up and keep the car rolling instead of making it slide..But no effect of the brakes will happen..Just make sure your fluid is full and there are no leaks and if you want to get them check you can stop by your local Auto Zone and they will scan your car for free and tell you what sensor is bad..I hope this was helpful to you...Have a great night

check the brake fluid level, if its low the light will be on. Usually when the brake pads wear down the fluid will become low and thats about the time to change the pads. You should be able to add some fluid though and be ok for a bit. If you hear any funny sounds like grinding or squicking (sp) then its time for brakes.

If the problem is that the brake lights will not turn off, the problem is most likely the CHMSL relay. An easy check is to take the cover off the fuse block mounted on the driver's side fender well and swap the fog lamp relay with the CHMSL relay. If that fixes it, just get a new relay for the fog lamps and you're good to go. Note, my 2002 s10 does not have fog lamps, but it still had the relay populated in the fuse block.
