Is it that nasty rotten egg smell?

Is it a Silverado body style? If so change your cabin air filter.

hi I was told from gm it was from your a/c before you turn your truck off shut a/c off and let fan run a few minutes .and you can use a/c system odour treatment

I had the samething in my truck.It was the cab air filter under the passengers dash,didn`t know I had one,it gets wet from the humidity,an over time,it starts to smell.When you change it out,theres coils next to the filter,try to clean them with a little bleach an water.Hard to get to!Do what you can.This should help.
