Brake lights do NOT work, 3rd brake light does, turn signals work, hazards work

Back in November my stop lights were no longer working while the emergency flashers, turn signals, and 3rd brake light were still working. The turn signal switch turned out to be the problem (at least temporarily). After swapping the turn signal switch in the steering column, the problem went away. Recently, someone pulled up next to me and told me that only my 3rd brake light was working again....so it's safe to assume something is shorting out the switch.

The first thing I did was check all of the bulbs and they are fine. Now I am in the same exact predicament as before..however, this time I am in no rush to replace the turn signal switch since something is causing it to go bad.

What could possibly be wrong with the circuit to damage the turn signal switch? I highly doubt that the brand new ACDELCO switch could have went bad after only 4 months..if not earlier since I was not aware of this problem until recently.

Any help or ideas would be greatly appreciated. Swapping the turn signal switch solved the problem temporarily, but now it will most likely have to be replaced again on top of a wiring troubleshoot.

What about the brake light switch that's connected to the brake pedal? Maybe that went bad?

If the brake switch was bad, the 3rd brake light would not work. It's primarily a problem with the turn signal switch since the hazards and stop lights both are on the same circuit. I have no idea what is causing this problem. After replacing the switch in the column, the brake lights worked beautifully for some time until recently.

I THINK there are 2 brake light switches the second switch that operates the 3rd light also operates the cruise and if the 3rd bulb is out the cruise won't work

did you swap out brake light bulbs to higher wattage?
you could pull all the bulbs then ohm out the circuit to see if its still got continuity to ground altho an intermittant short might not show up.

might take apart the old ts switch after replacing it and see what the slider contacts look like.
if they are burnt and melted the plastic around them then its excessive amperage, theres also always a chance it was just a defective switch and nothing else wrong.

You're having the same issue as before. The problem is wiring harness in the column for the turn signal switch. This a a very common problem on GM columns on all models. If you get down under the dash, you will find the white wire on the column side of the plug broken just after the plug. It is the wire on the "top" end of the plug, closest to the driver. What causes the problem is the that the wire is bent too sharply, which after a while causes the wire to break. You can try to pull the pin out of the connector, strip the wire and try to get it back in the plug, but often there isn't enough wire to do that. Usually, I've ended up having to replace the turn signal switch in the column. Not to bad to replace, last one took me about 2 hours to do. The biggest pain is snaking the wires down the column. If you have any questions, just ask.

Hey, but the turn signal switch in the car was replaced in November. Do you really think the brand new switch could have gone bad after 4 months due to a bent wire? I've checked the brake light switch and the harnesses for the tail lights/3rd brake light look fine.
