Hello and welcome to justanswer. My name is XXXXX XXXXX I can assist you with this.
Are you talking about the lights in this?
Yes the ones on the heater control panel. all of the buttons light up except for the fan control and mode and a/c button on the far right. however they do light up when you hit the panel. something is loose or bulb needs replaced but the shop keeps arguing that there is no light behind those buttons. EX version page 188 of the manual

Ok, that was the image I sent you asking if that was the one. These have bulbs in them that can be replaced.
See the image below.
