Grand Prix 2002 Brake Lights Don't Work - Center Works Side Brake Lights Don't Work


Asked by Oct 14, 2013 at 08:41 AM about the 2002 Pontiac Grand Prix GT

Question type: Maintenance & Repair

My 2002 Grand Prix center brake light works, but side brake lights don't. Tail lights,
backup, and turning signals all work.  I tested wires and no power at side brake light
receptacles when brake pressed, fuse is good (I only found one fuse for Stop lights in
fuse panel behind glove box), brake light switch good (there are two switches under
there so I've only replaced lower larger one - expensive).  Don't know what the higher
one is for with only two wires to it. Power at fuse tested good. I'm going to check the
steering column flasher issue discussed in another post next but I'm running out of
options. Can't believe a wire would just short - but maybe where they converge there is
a bad connection. I know in the trunk that 4 or 5 brown wires are connected to one. It
looks like my wire loom runs up the passenger side floorboard under the door kick
covers. Does anyone know - there are green black and brown wires to the tail lights -
which two operate brake lights? When I turn turn signals on and test green and black
and green and brown, both blink my test light.  Which two colors operate brake lights?  
tested across green and brown wires I found along passenger door kick and no power
there either.

The two switches at the brake pedal are for the brake lights and cruise control cancel. Check the wiring for the turn signal switch. Power for the outboard brake lights passes through the turn signal switch. But power for the high mount 3rd brake light does not. HTH. -Jim

Are you SURE that the brake light bulb(s) filaments are good?
