The install went great, the car starts remotely with 3x locks on the OEM key fob. The parking lights turn on, the car starts and all seems great. However, the HVAC controls are dark, driver/pass temp settings on both dials and all button backlights, yet the HVAC is indeed running. Typically these are never off unless the car is off or the HVAC is off. They always display the set temp for driver/pass regardless of the headlight setting or dashboard brightness setting.
Once I enter and switch the headlights to "auto", "parking", or "on", the HVAC controls reappear, but if I turn the headlight switch back to "Off", the HVAC controls disappear again. The only way to see the HVAC controls while the headlights are "Off" is to press and hold the brake pedal for 4 seconds, or shut the car down and start it up normally.
While all else seems to be functioning correctly, I'm concerned as to why the HVAC lights are off. What is causing the display/backlights to go dark even though the HVAC is actually running? I've been studying the nissan service manual but can't seem to figure out how that's even possible.

All of the button backlights are off as well, difficult to capture during the day. :)
