Above the brake pedal,its black plastic.
Switch is defective or out of adjustment.
Probably a brake light switch problem. May be able to adjust, or may need to replace. I just replaced the brake light switch in my 1998 Mazda Protege LX and the problem came back. I believe the cruise control could be shorting out the brake light switch.
Typically the light will remain on if the fluid is low, or maybe the ebrake just pulled just enough that it is on..... or the switch that is triggered by the handle is faulty
Remove the high mount brake light retaining screws from your Mazda Protg. Remove the high mount brake light wiring harness. Reverse the process to install your new high-mount brake light.
How do I adjust a stoplight switch on my mazda 626 LX V6
there is a brake switch under the brake pedal. This is a button that pretty much controls the break lights. you might need to replace this or look through the fuse box under the hood. (blue 15) is the fuse that powers the brake lights.
reset it.
I suspect your hold switch on the shift lever might be bad..or ahs a broken wire.
where is brake light switch
You have to go inside the trunk and remove the circular plastic covers from behind the lights. Then you have to unscrew the entire light and you can access the bulbs to replace them.
Fuse panel.
Bad ignition switch?
