Brake lights don t work

SOURCE: I have A 2000 Chevy 3500 Express Van and the brake

Hi,

When you said that you checked the brake switch, did you check it live? Meaning verified live power to the switch, press switch, and then power came out the other terminal?

If so, also verify zero power on brake press, at the offending brake light bulb terminal. You must verify the test light each time you move it...leave running lights on...

After verifying that there is no power coming, after the brake is pressed, note the wire color and find it where it comes to the steering column and test there... This would eliminate wires and connections between front and the rear of the vehicle, unlikely, but needs to be tested.

After verifying no power at that terminal, then yes the t/s switch is certainly suspece. This may be the time to get a mechanic to verify and replace the switch, there are locks, tilt mechanisms, air bags, column bearings, etc involved. Failures risk loss of vehicle control (locking or binding for example.)..

Hope this gets you going in the right direction.

Vehicle electric trouble shooting is the worst. Some of the problems you described the bulbs may have multiple filiments with only some burned out. It may sound silly but change the bulbs. Get a couple of new bulbs and try them in the different spots. Time, road vibrations and spring pressure causes the contacts on the bulbs to wear until they get a poor connection then you get a little arcing that build up a residue and a bulb that test good doesn't work.
Your on the right track with the ground wire. Try a test lamp with a good gound connection and test the different sockets, if your test light works but your bulb doesn't you have a ground fault. If neither work check the switch and fuse before you start tracing the wiring. These are just general trouble shooting tips It's very hard to trouble shoot electrical problems sight unseen.

My 1998 Express van brakes started smoking recently too.
I changed the brake hoses and the smoking stopped
