Why do the steering wheel buttons not work after replacing the center console screen?

[Ann]

The reasons for the malfunction of the buttons on the car steering wheel are as follows: 1. Functional failure: You can manually operate the multimedia buttons on the center console or the same function buttons/knobs on the touch screen to verify whether it is a functional failure. 2. Mechanical failure: Buttons are consumable components that wear out during use, leading to a shortened lifespan. It cannot be ruled out that functional failure and uncontrollable quality are caused by poor quality, unreasonable design, or immature manufacturing processes. 3. Circuit failure or connector failure: Buttons have corresponding matching circuits and connectors, plugs, etc., for electronic and electrical connections with the center console. Accelerated oxidation of connectors due to unsuitable usage environments, aging wires, oxidation of button contacts, short circuits, or intermittent disconnections can all lead to button malfunctions.
