A lot of electronics stopped working

[crunk]

So I was driving my car yesterday and when I parked in my garage, I realized a lot of electronics stopped working. I checked some of the fuses (normal) near the steering well, trunk and engine.

Here are a few Electronics that stopped working:

• Passenger mirror tilt, fold, and signal
• All door locks but drivers door
• Passenger window

Any ideas what might be happening?

The only reference I points I have is that it was raining really hard when I drove it to grab lunch beforehand. Not sure that would cause it but maybe it’s relevant. Secondly, the car was in a minor accident on the passenger side that was repaired before I bought it.

Could be something got wet or a bad connection. Considering that most of the stuff is the passenger door I'd start looking where things connect either in the door itself or in the body. Wiring diagram would help but perhaps someone here know where to look.

Assuming it's not under warranty (because I'm sure you'd just go to the dealer if it were), I'd first check the wiring boot in the passenger door to make sure it's seated correctly and not wet from the rain. Hard to say other than that, without a wiring schematic or taking the interior door panel off (which I've never done in this particular vehicle but most I've done have always been somewhat similar to each other).

Also, all those things can be controlled by the driver's door controls. Check there too.

I checked a bunch of fuses (all fine), checked the boot to the passenger door, and removed the passenger door panel. I didn’t see anything out of the ordinary.

You took the door panel off and dug around, huh? Nice work. You should post a tutorial for the panel removal. That's one of the most requested things on pretty much every car forum.

What about the control switch on the driver's door? I suppose it's possible that if it went bad it could affect those other things.

It was super easy. Below are the steps to remove the door panel on a 2015 Hyundai Genesis:

1. Open door
2. Remove the plastic frame around the window on the upper part of the door. There is a plastic screw clip on the front of the door. Unscrew it and remove. Then, lightly pull in the top corner of the plastic door frame and it will snap off. Removing it first prevents scratching the plastic when removing the door panel.
3. There are 2 screws that hold the door panel on that are hidden. I'd recommend a plastic panel remover tool or use a butter knife carefully.
4. The first screw is hidden behind the black piece of plastic behind the door handle. Slide the knife behind it by the door lock and pry towards the other side. Remove screw.
5. The second screw is underneath the small rubber pocket cover by the door switches. Remove the rubber liner and then remove the screw.
6. After that, the door comes off really easy. Just lightly pull out from one of the bottom corners and follow around the door. I think there were 4-6 clips in total.
7. Then unclip the electronic harnesses
8. Once the 3 screws are removed (1 plastic, 2 hidden metal), the plastic window frame cover is removed, the clips are out, and the harnesses are unclipped, you can pull the door up from over the window sill

This is a good video. After doing it, the 2015 Hyundai Genesis was identical.

Also, if you want to further remove the plastic panel, you need to lower the window ~ halfway, remove the two bolts that hold the window down (behind circular rubber boots), remove the window ,disassemble to door lock, then remove the ~8 10m bolts holding the plastic panel on, and unclip any electronics. Then you'll be staring at the hollow part of your door.


Hope that helps.

Awesome. Thanks for posting that. And I can't believe I didn't check YT to see if there was one out there already. Guess it's not that important until I have to do it myself...

You know, anything electrical on this car could very well end up being a bottomless rabbit hole. It may be worth it to pony up and pay the labor to have a dealership hook a scan tool up. Just a thought. Without a doubt that's what I'd do. Well, I'd at least call them to get an estimate on the time it would take and what their labor/hour is.

Haha no worries. There isn't a whole ton on this car on Youtube.

And how long have you owned it? Reason I ask is I just bought a '13 Sedan myself and it had an "installed" electrical problem that manifested after having it 5 days. Easy fix, but still. By Installed problem I mean to say someone installed the battery and never tightened up the Pos post and killed the battery as well as it did *light dances* in the cluster along with fail to start to alert me to the issue the first time.

ETA: to say first an only time. i went home and found the issue, fixed it and all good.

Just got back from the dealership. Problem was embarrassingly simple.

There is an electrical harness connector on the body of the car by the door hinge. It wasn’t seated all the way and the door wasn’t getting power. I thought it was just a pass through boot...

If anyone runs into electrical issues with the doors,windows, or mirrors definitely ensure that the connector is snug.

Great that it's fixed though.

Let me tell what embarrassingly simple really is.... My Miata passenger power window stopped working. Before I had a chance to take it in for troubleshooting, I made the mistake of lowering my top; doing so drops the windows 2 inches. After raising the top, the window was stuck open 2 inches, and yes I had rain before I finally took it to the dealer. Problem? You guessed it: I had accidentally pressed the power window lockout button on my armrest, and I had completely forgot about its exsitence, so never even checked that. ON the bright side, it was due for an oil change, so at least the car benefited from that.

Also, that's valuable information (knowing that there's a connection in what appears to be a pass-through boot, so thanks.

Agreed but they still charged $280 for it

Yeah, that sucks. Sometimes you just have to take in the exit hole when the dealer gets involved. But everything is working now and that's the important thing.

I think that you should check all the fuses in the car and see which one is burned. There can be other cause but I don't think so. It also maybe the belt from the engine, which is charging the main battery. So the battery could just shot down because it had no source of energy. The last cause can be the pcb, recently I studied a guide of understanding circuit boards. So there I read that pcb can cause the shutting of the whole electric system. I think you should check the guide because it is worth, then you can take a look at the broke pcb.
