SOURCE: 1990 geo prizm brake lights only work when car is off

Some vehicles only allow the brake lights to work when the ignition is turned on and control this via a relay which may have failed so the function is reversed allowing them to work only with the ignition off. Relays can 'weld' their contacts together causing them to become non-operational.Check in the central (if so equipped) fuse/relay box; if you are lucky the cover will have a diagram of the fuses and relays.If so, locate the relay for brakes, check the part number on it, exchange it with the same part number from a different function and try (while parked) to see if this has cured the problem by turning the ignition on, tapping the brake pedal to see if they now respond.If so, the original brake relay is bad.

My 1990 geo prizm brake light comes on when I start to stop and turns off when I stop


You need to replace the brake light switch, it is located above the brake pedal and is actuated by the brake pedal arm.

1995 geo prizm ebrake light is on. Is this a faulty sensor? I heard it could have an brake indicator wire that makes contact with to let you know youre pads need to be changed.


Your brake pads don't have any kind of wire going to your brake pads that will make the brake light come on, check your master cylinder for low on brake fluid, if low look in back of tire's for wetness, if none, top of master cylinder with DOT 3 brake fluid, and have your brake pads checked for wear.

Brake lights not working, fuse is fine bulbs are good all else operates fine, signals, back-up lights, etc all good. 2007 Kia Rio 5 hatchback


Check the brake switch above and behind the brake pedal. It may have slipped out of position or could be faulty. It can be tested with a meter.

Brake and parking lights


It has been my experience that the type of problem you describe is usually caused by a bad ground at one or more of the lights, or by a bad chassis ground. I suggest you first ensure that the battery, chassis, and engine grounds under the hood are good. If they are you might try pulling one lamp at a time to see if you can find one that when pulled, the rest work normally. If you find that lamp, your problem is there. Good luck

Geo Prizm brake lights


I had the same problem, what I did to fix it was as follows:
  • Removed the plastic light holders from the tail lamp.
  • On each of the three bulbs there is a ground wire that is attached to the plastic light holder via a screw. Remove these connections and clean, I used some very light sand paper.
  • Reassemble, Worked like a Charm for me, and I save a $90 charge from Firestone by doing it myself...
