When I turn my car on. The screen is completely black. I can’t turn on the radio, heat, A/C, nothing. It is still blowing out hot air. I can’t shut it off.
It's for the vehicle listed above SL model, 3.5L, six cylinder.

Hello,

It sounds like you have a problem with the CAN (computer area network) which needs to be scanned. here is a video of the job being done. It also can be one of four fuses can be out (15, 65, 30 and 29) in the interior fuse panel. Can I ask if the steering wheel controls do anything?

CAN scan video:

Here is a guide to help us check for power at the fuses and the fuse locations as well. Also, I have included the radio and media display wiring diagrams so you can see how the system works.

This guide will walk you through the steps the diagrams for your car are below:

Check out the diagrams (below). Please let us know what happens.

Thank you so much.

Everything is almost look like normal: no warning, unless something: sometimes " key ID incorrect", sometimes the door manual lock unlock doesn't work, and if I open the door-back: it opens and closes itself unless I block it by hand. The the steering wheel controls works fine.
I have already checked the fuses, the connectors, the wiring and they are good.
For more information, at the beginning of the problem, the screen went blank when I turned on the engine and then it came back on after about 15 mn of driving and worked well; but it turned back off when I turned off the motor and went back on again after 15mn. So the back on of the screen became longer after and then it totally stopped after few month. It is on but no signal.

So I would to know which relay (may be some contacts carbonized) should I check or if there is some part like thermistor or other parts changing with the temperature over there.

Thank you again.

If the power and grounds are all okay it sounds like the display itself has gone bad. I would try to find a used one to save some money. Here are diagrams below to help get the problem fixed. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Good morning,

Most likely the screen was the issue for this.

We did not hear back but that is the most common issue.

I have a similar problem with my 2014 Nissan Pathfinder. Whenever I start my car, the display would sometimes turn on or not. When it turns on it stays on. When it doesn t turn on it stays off and I would have to turn off my engine and restart to see if it would turn on. Basically whenever I turn on my engine, it s a hit or miss on whether my display would turn on. This is really annoying because if I turn on my ac and leave it on when I turn off my engine. Then next time I turn on my engine and if the display doesn t turn on, my ac is stuck as on and I have no controls for radio, display, ac, ext.

When the display is on it works fine.

Any help is appreciated.

I attached a photo showing my engine is running but display didn t turn on.

It seems like it s very randomly whether my display would turn on or not whenever I start my engine.

Yep, this happens when the accessory relay is going out inside the right-side relay-fuse panel. Here is a wiring diagram of the display so you can see how it works with the relay location as well. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Hi Ken, I appreciate your response, but it is way too technical for me, lol.

Could this also be related to a bad alternator? Reason I asked is my alternator just shut off with no prior warnings.

It could if the battery is running low. Here is a guide to test it and diagrams below to show how to change the alternator out:

I am having this same issue. The screen is dark, but everything works (including the actual touch screen itself - it responds to touch, but it's black so you can't tell what you are touching). I was planning to buy a used one and replace it myself, but I read somewhere that it has to be custom configured to the specific vehicle by the dealer. Does anyone know if that is really the case?

I haven't done the replacement yet, but as I was driving around, I noticed that I could see the display in direct sunlight. It would appear that the issue could be with the display backlight. I pulled a few fuses from the interior fuse box that seemed like they could be related, but they are all fine. Any thoughts on a fix for the backlight before I replace the entire display?

So, that's what happened: the illumination driver inside the screen had gone out but the LCD readout was still working. It still needs to be replaced.

Any fixes? 2018 Pathfinder did something similar black screen no radio either. Weird part is the backup cam shows on the screen still just lost the prediction lines.

This can be one of two things either the display has lost that ability, or the rear camera is not recognizing the lines, I would get a CAN scanner to run the body codes to see what's up. It is easy to do. You can get a CAN scanner (Controller Area Network) from Amazon for about $36.00.

Here is a video to show you how:

and

Amazon CAN scanner link for about $36.00.

Let me know what codes come up so we can fix it.

So that could likely resolve the radio not to work at all also? All the display is doing right now is black screen nothing else but rear cam view. So, we know by that, it's not the display. No welcome screen, no functioning radio/audio or ac display. Weird right! Thanks for your time in advance.

Yes, it can because the system is interrogated. I would get a CAN scanner to be sure though. Check out the wiring diagrams in the post above to see how the system works. Let me know what happens please.
