Yea it was! Ordered one from GM parts based on the other post. When I went to replace it, turns out the plug had worked loose. Put the plug back on and it worked perfect!!
I have a 2021 2500HD and the Cargo/Reverse light on the passenger side mirror quit working. Dealer told me the only way to fix it was with a new mirror at $1400 bucks. Does anyone know if there is a way to fix it with out a new mirror? Thanks in advance!
