If you're wondering why your GMC Sierra's steering wheel buttons aren't functioning properly, I can provide some insight into possible causes. A common issue that can lead to unresponsive controls is a faulty clock spring. The clock spring plays a critical role in allowing the vehicle to send electrical signals to the steering wheel components, including the controls. In most cases, when the controls stop working, it's likely due to a malfunctioning clock spring. Another potential cause could be a malfunctioning control module. It's advisable to have this issue diagnosed and remedied by a professional auto repair shop for proper resolution.
The steering wheel controls on the 2019 GMC Sierra might fail to function because of a defective horn switch or blown fuses.
