Replaced CHMSL/3rd Brake Light.
Hit 76000 miles today.
Received build sheets for both the NBS and NNBS today.
About 13 months ago, I replaced my CHMSL with a Dorman LED light ordered from Amazon Prime.
Then I find out that the light is out again. After a few posts on the NBS thread and some trial and error, it turns out that the light itself appears to be the culprit, so I ordered another one to replace the dead one.
The 10amp fuse by the drivers side had blown and kept blowing when I plugged the light in. Even though it would not illuminate.
I had all the tail light functions with or without the CHMSL plugged in and I metered 12 volts at the plug.
I pulled the grommet and the wires out as far as I could, but was not able to find any indications of water intrusion, corrosion or chafing that might point to a grounding issue in that location.
The Dorman light comes with a replacement harness, but I wasn't entirely happy with the grommet fitment, so I left the OEM harness in place as there didn't appear to be anything wrong with it.
I installed the new CHMSL and am back in business again. Hopefully this light lasts longer than the previous one.
I took her for a spin to Home Depot today as it was sprinkler repair day and hit 76000 miles on the way.
I also received the build sheets for both the NBS and NNBS from GM Customer Service. (Just send a PM to them with your VIN and email.)
And some pics.
