Nissan Titans have reused many of their interior lights from previous cars.
Even though there are very few new cars without push button start, Nissan is trying to stay competitive in this evolving market.
In practically any car, there is a ton of light in both the interior and exterior.
For the interior lights, you have the dome lights, map lights, door lights, dashboard— and this is just a partial list.
Newer cars or more expensive cars should have more features, not necessarily more lights.
The exterior lights are more obvious since they are literally talked about and required by regulators to be functional and operational.
In this article, we will discuss why your Nissan Titan Interior Lights aren’t working—
- Body control module is malfunctioning
- Check your fuses
- Check your bulbs
- Wiring Issue
- Light harness connection
Body control module is malfunctioning
The body control module is located inside of the firewall, near the steering column in your Nissan Titan or the right side of the passenger glove box area.
Here is what you need to check—
- Fuse #15 – If this amp fuse is good, then your entire BCM is the issue.
- Fuse #22 – Provides power to the BCM for interior lights, on the lower right of the fuse block dash
- Fuse #19
- Fuse #55 in the IPDM
- Fusible Link F in the Fusible Link
If it is a body control module issue, it falls under an electrical issue that is variable with each specific car.
These issues are rare especially if there were no traumatic events that occurred to your Nissan Titan.
And on the flip side, this is what you should also be keen on looking for.
Check your fuses
It is very common to have a blown fuse that does not allow your Nissan Titan’s interior lights to turn on.
It is also well-known that your rear interior lights will have a blown fuse.
Replacing the fuse will correct the problem immediately.
It could be a blown cargo fuse.
Or for instance…
The blue square could be where you have blown a fuse on your BCM.
For orientation, the positive battery terminal is connected on the right lower side of the diagram.
Maybe you checked all the fuses in the Nissan Titan and in the hood but nothing seems to be blown.
Sometimes, the issue (and its solution) is right in front of us for us to figure out.
Check your bulbs
If your BCM is in good condition, it could be possible that one of your lightbulbs has malfunctioned and requires a replacement.
LED lights today—
- Are brighter
- Lasts longer
- More Efficient
This is compared to the older version of light bulbs.
Do yourself a favor and upgrade your bulbs.
If the problem is not the bulbs, it could be the wiring that leads to your lights that is faulty.
Here is what could have gone wrong—
- Child lock not releasing
- Link inside the handle to the lock of assembly is not engaged
- Missing interior cable connection to the handle
- Crimped wire above the overhead console
This may require you to remove the door panel for inspection.
But if you are experiencing blown fuses constantly, this is not normal.
An unstable wiring issue will disguise itself and cause consistently blown fuses ever so often, let’s say every time you hit a bump or something.
Light harness connection
This is a rarer issue but maybe when the front passenger light harness was reinstalled, your Nissan Titan interior lights did not turn back on.
One solution is to try to move the wires around by jiggling it and trying to see if that makes a difference.
For some owners, this does the trick, indicating a loose connection.
What causes interior lights to stay on?
- If your doors are open
- If your dome switch is on
With those two conditions, your interior dome lights create a complete circuit for electricity to power your interior lights.
A completed circuit is what will make your Nissan Titan interior lights come on.
How long can interior lights be on before the battery dies?
With good batteries, your interior lights can be on for several days without having a dead battery.
X2 Power vs Odessey battery… what is your pick?
- X2 Power – 76Ah (20 hours)
- Odessey – 65Ah (20 hours)
Both are great and they should last you years, if not decades if you are proactive about your driving.
Since most normie car batteries have around 50Ah, it would usually take 25-40+ hours to really drain a normal battery with just the interior lights on.
With the high-powered batteries mentioned adobe, expect longevity and excellence.
Another thing to keep in mind is that batteries should not be draining within 8-10 hours after a fresh installation.
There are some owners that just keep having battery issues and I am here to say that that is atypical.
For a Nissan Titan, you may notice that your LED lights perform LED ghosting, which is when your switch is in “door”, your LED lights are dimly lit instead of turning off.
Though this will draw some power from the battery, the only way to completely eliminate this annoyance is to add resistors or reuse the stock bulbs; neither of which is optimal or worth the hassle.
This will not prematurely destroy your battery since your Nissan Titan is more resilient than that.
Wrapping It Up
There are not too many things that can go wrong with Nissan Titan interior lights.
It really just boils down to a few things:
Likely, nearly all cases will fall into those three options but you may have the few where there may be bulb issues or light harness connection issues.
But even with these minor issues, it is great to know that the Nissan Titan can run for very high mileage.
At least it is much better having a Dodge Charger interior lights issue.
But enough about having issues with your cars.
Let us focus on better and brighter aspects of history— like the best Thunderbird cars.
