Heated/Cooled Cupholder Question




Quick question for anything with a heated/cooled cupholder who had it as an ORIGINAL option.
Does your cupholder light up no matter what time of day it is? IE -- are the yellow (solar) lights on at all times of the day, no matter if it's dark or not?
Asking because I retrofitted mine with the proper wiring harness, and tapping into the cig lighter for power. It's 4 plugs -- 3 x 12v's and 1 ground. Ever since I installed mine, it would illuminate when the truck was on, and when entering/exiting vehicle (would turn off after 30 seconds or so, timed with the interior lighting). About a week ago, I noticed it stopped doing so, only illuminating in low light conditions / headlights were turned on. So I'm just trying to determine whether or not that's how it should work from the factor, or if my wiring harness/retrofit may have a short in it somewhere.
THANKS!!












Because part 2 of this is I added footwell lighting to the truck as well (as I also retrofitted ambient in my truck with all OEM parts etc (see my other thread). When doors would open, no matter if dark outside or not, the footwell lights (tapped from the front cig lighter) would power up, meaning juice was coming to the cigarette lighter. But now, it's only when the truck is on.
My door/dash ambient light continues to behave as expected though, only coming on when headlights are on. INTERESTINGLY though, my dad's 2012 ML (with 876 installed from factory), ALWAYS has the ambients in the doors on.

The fix only took an hour or so if I remember, so it’s nothing complicated.
Vid is of what it should NOT be like

If so, I agree, and that is what mine was doing originally after installing, but suddenly has decided to stop.
