Rear Defogger Switch back light

[BPiston]

2020 Canyon.    Back light for rear defog switch no longer illuminated.   I am assuming it is a built-in LED and not replaceable.  So I am planning on replacing the control/button assembly.  (Maybe I should wait until more bulbs burn out) If I do replace the control head, will programming by a scan tool be required?    Thanks.

Nope.  Would be a simple remove the old control and install the new one.

We may deal with the intermittent back light issue on my uncle's new 2020 Canyon. It illuminates intermittently so it may go out soon. Got to finish installing the rotors and moto metal wheels on the Silverado this week before the new owner could fetch it and take the Canyon in.
