2014 power driver seat, power mirrors, power pedals not working

[Jcoiteux]

My 2014 SLT just had the drivers side seat, power mirrors and power pedals quit working. The passenger seat works fine. Interestingly, the auto mirror tilt is not listed under vehicle options anymore- it used to be able to be toggled under vehicle>convenience. I've checked the fuses that make sense and they're fine. i'm not sure if there's a fuse that is controlling all of these components that I missed. I have not checked every fuse in all (3) fuse locations. Any help is appreciated- thank you.

I just had this exact same problem with my 2014 Silverado Z71 SLT.

I also lost my lane departure warning vibration and the option to select the type of warning disappeared from my settings menu.

The local Chevy dealer wanted $150 to reprogram my drivers seat control module.

I disconnected my negative cable from my battery and let it sit for a couple of hours and reattached.

Everything works perfectly again!

So what was the cause and the fix? I know it’s been 5 years but hopefully I will get a response

Had the same issue.Take off battery terminals for 60s. Reconnect and this will reboot all modules on vehicle..

Fixed my issue.
