Electrical problem
2005 Chevy Silverado V8 Two Wheel Drive Automatic 32500 miles

my brake lights on my bed do not work, but the cab brake light does. The flashers will work and turn indicators also. So I know its not in the fuse, and changed out both bulbs

Do you
have the same problem?

Sounds to me like you have a burned circuit board for the brake lights, does yours all share the same fillament for turn signals/brakelights/hazards?

I am having the same issue also, just found out a few days ago.

2005 silverado. Brake lights do not work but all other signals and the cab brake light works.

Tested everything, switch is fine, receiving power to the fuse panel under the hood and in the cab fuse. Grounds look good, bulbs good. No visible wiring issues.

What would you recommend as a way to test the switch? I have spend 8 hours testing every wire in/out of the turn switch and the fuse panel to no conclusions. I tried jumping across the switch itself to no success. Tried unplugging it to no success.

The white(brake power) is good coming out of the switch going into the fuse panel and into the turn lever itself. The CM brake light tests good. The rear brake fuse jumps up and drops back down to zero on the multi meter. Testing the backside of the fuse panel blue wire tests good 12v when pressing the brake pedal which is odd. From the wiring diagram all this doesn't make sense. I am looking for a way to make sure its the switch itself before purchasing one. Any ideas would be appreciated.

anyone figure this out yet?

Its a bad turn signal switch. The brake lights run through the turn signal switch, if switch is bad you will have no brake tailights but you will have the cab bed light.

Get the junk yard part, oem is way to expensive.

Guys, did anyone solve this? I've seen a couple of threads on here but no solution that I can see.

Can anybody say what the solution to this problem is? I have the same problem. Seems like there is a lot of this.

Same situation for me, silverado 2003, 1500,

Dan

Hey guys,

There is a fuse that runs just the lower brake lights, here is a guide and some wiring diagrams to help you trace the problem down. Check to see if there is power at the brake lights to see if the problem is a ground issue.

Please run some tests and get back to us.

The brake lights on the bed are not working. However the brake light on the cab is working. I replaced the bulbs and I checked the fuses, but that was not it. Please help me figure out what to do?

First question I always ask is; do you have a trailer connector spliced in behind the bumper? 75% of the time, that's where the problem is. Please advise.

I believe I have one but it is factory installed. Does that make a difference? And, what in particular would be the problem there, a short or is there a fuse there?

You will want to test your trailer connector to see if you have brake lights there. You're looking for an "open" in the circuit somewhere. The brake light switch has to be functioning or the cab light wouldn't be working.
