Hi everyone. New member here.

I recently installed an aftermarket stereo in my 2010 Nissan Titan Pro-4X. Today I noticed that the lights on the AC controls, the gear shift, the rear sliding window button, and the buttons below the AC controls don't light up anymore. (I am including photos of all of the lights that are not working.)

The AC and heat WORK fine, and when you press a button (foot well only, head and foot well, etc.) light up to show you which you have selected. The same thing happens with the buttons below the AC controls. The rear sliding window works fine and so do the steering wheel controls for the stereo.

I have checked every fuse in the car and under the hood and none of them are blown. The overhead lights, gauge lights, window switch lights and stereo lights all work fine. The dimmer switch works as well. I have also checked all of the connections to the AC controls and to the stereo and they are all secure. I have even checked the illumination wire that goes to the back of the stereo and that is tight as well.

I have seen others say that the solution is to turn and jiggle the dimmer switch, but I have tried that a few times and it is not fixing the issue.

If anyone has any ideas on what this could be, please let me know as soon as possible. I would love to get this fixed!

Cheers!

Maybe it has something to do with the stereo installation. If you unplug the stereo, what happens to the lights?

I thought the same thing, but after spending literally a day and a half on the phone troubleshooting with Crutchfield we came to the conclusion that it can't have anything to do with the stereo install and must have something to do with the Controller–area network (CAN or CAN-bus). This apparently controls different electronics in the truck, some of which are the different lights.

They suggested that I take the truck to someone/someplace with a scanning tool to check to see if maybe the CAN-Bus needs to be reset. I'm hoping this is the issue and not something more as it sounds like it could be very expensive. LOL

I will post after the scan and let you know what I find out, but if anyone has any information/thoughts/experience with this, PLEASE chime in. The lights that are out right now are not a big deal, but I would like them to work properly just because they should work properly. :)

I figured it out today!!!!

Under the hood, in the big fuse box next to the battery, there are a bunch of fuses. They are kind of tucked back on “the wall” of the fuse box and for some reason they are not labeled on the lid of the fuse box.

If you are having this lighting issue, check here First! 😁👍


The fuse with the blue square around it is the one that was blown and the one that controlled the interior lights I was having issues with.

For reference, the below picture is of the entire fuse box. Notice the red square at the bottom right side of the pic (that’s the positive battery terminal)
