2014 Chevy 2500HD. Still working after a year being installed
2014 Chevy 2500HD. Exact GM original part. Been on the truck for a year now. Haven't had any more issues and it's working as it should. Been working on vehicles for over 30 years so this was easy for me to remove, test and replace.

Quality part
Installed in a 2016 Duramax 2500hd and solved my problems which was an engine light for redutant tank heater. Confirmed it works with scanner. Good product!

Real OEM part, fits great.
The real deal GM part here- fits properly and solved the problem. I had replaced the original with a Dorman part because that was all I could get at the time- and it failed after 3 months. This part is the original, and my original had lasted 140k miles and 12 years.
