BRAKE LIGHTS DON'T WORK BRAKE SWICH CHANGED BULBS CHECKED AND INSIDE FUSES OK

SOURCE: Brake lights quit working.

if all fuses and bulbs are ok get to the brake switch and see ifits stiff or stuck, if it just has two wires on it you could join themtogether to see if the brake lights come on though obviuosly dont leave them joined.Good luck davelee

SOURCE: bottom brake lights and hazard lights do not come on. All other lights work including top brake lights. Fuses and bulbs checked.

Check for power out of brake light switch by brake pedal. Of its faulty , the 3rd brake light will still work. Hope this helps

SOURCE: No brake lights on 95 Suburban

Disconnect electrical connector to brake switch brake located near brake pedal. Check for twelve volts or power with a test light on one side. If power, get a piece of wire, strip the ends and plug into each end of connector. If brake lights works, switch is bad. If not, check bulbs and power in the brake light socket. If no power, check to make sure power is leaving the trafficator switch as the brake light switch is depress or bypass. Check for broken or bad connection along circuit. If all good, you could have a trafficator switch problem. Oh, are the hazard and trafficators working in the rear? If they are, the trafficator switch is bad because the brake switch sends power there, then out to the back through the left and right rear trafficator wires.

I have notice that this is a common problem. The socket most of the time goes bad, I don't know why but they just do. You can pick them up at any parts store for around 5.00 each. If you don't have a volt meter and ground straps to test it right, then I would try changing the sockets out. Quick and easy. Let us know how it goes.

you probably got the wrong bulb
those are usualy a different number higher wattage, they look exactly like an 1127 but are a 2027 or even a 3027 check the bulb base it has the number printed on it
