Hazard lights STUCK ON & I cannot turn them off! 😮

[TeslaFANa]

I’d like to report that I was able to find the issue, isolate it and address it so that the hazard lights turned off. It’s important because if someone else comes across the same issue, I want them to find the solution as well.

Upon having the front windshield tinted, a little bit of water got inside of the assembly unit above where the hazard lights are located. Since it is a sensitive hazard light button, I’m assuming that the small amount of water underneath caused it to malfunction.

I removed the assembly carefully, and unplugged it, took it inside my home and sprayed some isopropyl alcohol on the inside and used a blow dryer and compressed air to get any residue of water out from the inside.

After giving it about an hour to dry and plugging it back in, the hazard light button was responsive again and all is well. I hope this helps for anyone else that might get into a similar situation after having their window tinted.

This is extremely invaluable, thank you so much for not only solving the issue but also posting it here. This can save so many headaches to other owners including unnecessary trips to the service center. I live 2 and 1/2 hours away from my nearest service center so whenever I have to take my car to the service center it takes me 10 hours away from my family or work.

By the way, can you add an update to your original post, I find that very helpful so you don't have to scroll through many posts to find the solution. Thank you so much again, keep posting.

The hazard lights are supposed to keep operating even when the rest of the truck is dead, so it sort of made sense that they'd be able to operate independently of the truck's main computers.

So your working theory is that the moisture was making it act like someone was pushing the button repeatedly?

Correct!

I’ve tried all of the basic stuff like a soft reset using the scroll wheels, powering down the vehicle using the touchscreen. I’ve even gone as far to unplug the touch assembly control unit following the instructions in the owners manual (found here).

UPDATE: I see you dried it out to solve it. Leaving this here in case folks want the link below for other reasons.

I'd do a "hard reset" by disconnecting the MV/48v battery for a couple of minutes. I've had to do the equivalent on my TMX to reset some 'subsystems' that the soft reset does not (ie. GPS).

Service manual: "Disconnect MV Power"

You’re very welcome and great idea, just did that!

Better than breaking and not being able to get off the road, but not drivable as-is, get them to fix it so you can drive, waited long enough.

Thanks for the post. The same issues after my tinted window. My Cybertruck was towed to the service center 2 ddays ago, and the technician told me they needed at least a few days to figure out what was wrong.

You’re very welcome and hopefully they won’t charge you once they find out what happened.

Unfortunately, they asked me if I tinted the window recently and they found water spots on the control module. I have to pay in my own pocket.

Oh no!!! What exactly are they charging you for? The component dries out after about 24 to 48 hours depending on how much water is inside, and then everything would work normally again.

I’m confused too. But I sent the bill to my tinted shop.

how much was the fix? I guess tint shops will just need to be extra careful with cybertrucks.

I got my windshield tinted and when I picked it up, they had the same issue and couldn’t figure out how to turn it off. Kind of surprising that there isn’t another way on the screen to turn this off.

So I’m a bit impatient and didn’t have time to wait for it to dry on its own. I tried putting the controller in a bag of rice for awhile, but couldn’t wait any longer. This is my primary vehicle.

I took it apart, took the screws off to remove the sides of the controller and had to pry off the middle section which was difficult but doable. Then I blew air from my compressor in every nook and cranny and I saw a little water coming out with bubbles. After putting it back together, I was able to turn it off and it was working again!

TLDR: Save time by taking it apart and use an air compressor.

You can't turn off what's being shorted on.
