- 2020 Sierra 2500 windows rolling down

  Thanks for the responses. It may well be related to the key fob unlock function - the truck unlocks itself driving down the road as well (neglected to mention in first post ;o((. I have a real basic model doesn't have the auto window rolldown function so nothing comes up on "settings" (or anywhere else I can find). Holding the unlock button didn't make window roll down happen either. I guess the electronics might still be installed but disabled for my base line truck. I put the fuse back in so all windows work from the driver side, now but the lock function doesn't work at all on driver side. Unlock does work from drivers' side and lock does work from passenger side. I am not at same location as other key fob, so we'll just work with key only for now. The fob I've been using has been relocated to away from truck and that seems to keep windows up. A new fob is expensive, isn't it?

  Remote window operation is on. Your fob is being activated in your pocket and is putting pressure on the unlock long enough to trigger the remote window down feature. You can turn it off in the vehicle settings. Or, if you want it on, consider changing where you are putting your key fob on your person.

  After nearly 3 years of waiting I finally got rid of the chrome wheels. They were just too much. Next are the factory running boards. Very functional and sturdy but too bulky and they stick way out. Just my opinion anyway.

  Go into vehicle settings and see if it is activated.
