Yes, that makes sense. The CHMSL is not affected by the blinker circuit. It is also a much lower current circuit because it runs LEDs which use hundreds of times less current than light bulbs. If there is some sort of brake light within the windrestrictor (I was unaware of this), then the CHMSL circuit would be the place that would make the most sense to connect it to.

The Windresrictor has a Glow Module that works with the brake light so it would be equivalent, as far as draw goes, to the CHMSL. It works fine so the problem has to be between there and CHMSL. Tomorrow's weather looks better so I should be able to get at it. Stay tuned.
I should have listened to your advice from the get go. I did not expect a car that is only three years old to have a connection that corroded. Seems like a very poor design. Not only was it corroded but when I pulled it apart, the pin broke off. I was able to fashion another pin and all is well.
Go ahead with your "I told you so's", I deserve it.
No 'I told you so' here...just glad it worked out. Spray that connection with something (contact cleaner, WD-40, whatever) to keep from corroding in the future.
RRIX, I have a practically new third brake light unit that came off my 2008 vert when I put a spoiler on the car. It is yours if you want it. Just reimburse me for the shipping.....

Thanks but it turned out to be a corroded connector.

wildmanht - I could use that 3rd brake light. I have family in Mission Viejo. I could arrange to pick it up from you please email me if you still have it @ redleger@gmail.com
I have a 2013 C6 GS with the factory ZR1 spoiler which has the 3rd brake light. The LED works fine, but always stays illuminated ever so slightly. Could this also be corrosion in the connector causing it to stay dimly illuminated?

Yes, that is one of the symptoms of a connector problem. Just follow what you see in this post and fix it.

Thanks for the fast reply. Is this usually corrosion where the harness connects to the LED brake light assembly or is it further down in the harness where it meets the taillight/brake light main harness?

It's the main harness connector, shown in post 25 above, which is located below the outside passenger side tail light.
Third Brake light is out...just ordered a new one light assembly thinking it may be the bulb inside the strip...nope. Still doesn’t work. So I start digging and go into the main connection, and noticed no corrosion, but a pin is missing....I turn it over and notice there’s no wire going to that missing pin at all just a green rubber stop. Normal or no? You can see on the female connection as well when you turn it over it has the same thing a green rubber stop no wire for that pin....
Guys ever see this before?
So is this normal or should we see 8 pins and a wire from the male and female connectors out of each pin placement?
if this is normal, I have to keep working on this because it’s still not working....
From memory, yes 7 pins are correct (X455 Connector ??). The missing pin would be there for Rear Fog Lights required on European models.
I'd start by checking for 12VDC @ the 3rd brake light connector (3-pin & light blue wire, same as from x455 ??) with the brake pedal depressed. If good, it shares the same ground with all the rear lights that mounts to the B-Pillar right side under the interior trim panel. But, since it's the only light affected, it would be a possible ground break before there. Otherwise, a bad ground should affect all of the rear and rear side lighting.
If you get to technically looking for it reference CHMSL (Center High Mounted Stop Light)

Really appreciate the response thank you. I’ll start with the tips that you provided.
