Re: 2005 chevy 2500 brake lights wont work
Just to be sure you checked fuses underhood? There is a junction block at rear of truck on frame it can cause lights to not work check it to make sure all conections are tight.also check the trailer hook up for brake light power as this is on a seperate cicuit but is supplied by brake switch.If you have power there it will eliminate switch.your fuse box has a brake fuse and trailer brake fuse

Since the turns work in the back, that means the brake bulbs are good. Brake lights and turn signal lights share the same filament in the bulb.
There is a fuse for the brake lights. Then, there is a brake light switch on the brake pedal. You need a voltmeter or test light, after checking that fuse is good. Need to check if fuse has power on it. This is one of those fuses that are hot at all times-as long as battery is connected, voltage should be going through the fuse and up to the brake light switch. Check for power both places. The switch on the pedal is a simple on-off switch. When brake is depressed, the spring loaded switch is turned on-passing power on towards the brake lights.
But then the brake wire goes into the turn signal switch before going on to the brake bulbs...however, since your turns work good, I doubt if there is a problem in the turn switch. First check if the brake light switch is sending power on when switch is on.
Let me know what you find. Good luck.
i dont know where you looked and got your misinformation from. the fuse for a 2005 malibu brake lights is a 15 amp fuse located under the hood in the fuse block. the fuse block is located near the battery.
Check for power in and out of the switch with brake pedal depressed.If ok check to see if your hazard lights work you could have a faulty turn signal switch your brake lights feed through the T/S switch.Also make sure your bulbs are good.
I just Know that you replaced the bulb ,try a test lite ,make shure it's grounded well poke inside the socket for the bulb this metal socket gives the bulb both electric and a ground ,this is the problem,good luck.
test your brake switch located on the brake fulcrum. you can unhook the wires and usea paper clip to connect the two wires together if the brake lights come on then replace the switch, if it does not come on and the bulbs are ok then replace turnsignal switch.
Was the replacement bulb purchased an orignal equipment manufacturer from a Chevy dealer or a parts store.
Some aftermarket bulbs do not meet OEM standards and can cause this type of problem. A good parts store will carry OEMreplacement bulbs.
If it is the correct OEM bulb, we can go from there.
Let me know.
It sounds like you should check for power at brake pedal switch. Hook up a test light to the switch and press the brake pedal. If the light does not go on and you have power in the wires to the switch then the switch should be replaced.
I hope this helps you out
