Puddle lights

Teslas have the window motor and the puddle lights wired in series. So if your puddle light stops working, the window motor will stop working too. Therefore when you open the door, the window won't roll down, causing it to break. That won't be under warranty. But the rest of the car will still be under warranty.

The other issue I have seen with many aftermarket puddle lights is they eventually fade and look like shit.

>Teslas have the window motor and the puddle lights wired in series. Nope. This is wrong. >So if your puddle light stops working, the window motor will stop working too Nope, this is wrong too. As a matter if fact, when you unplug a puddle light the window motor then pushes the glass up, then drops it again, when the light, or new light is reconnected. That would be kind of hard to do if they were "wired in series." On the other hand, the light absolutely influences the window motor. There's car controller logic involved, but "wired in series" does not describe it at all. If you'd like to better describe this action, or interaction between the two, I'm all ears. If there's a failure mode where puddle light failure can fail the window motor, I'd love to hear about it.

It seems like I indeed oversimplified it. I've just heard many horror stories about this, and the explanation was always along the lines of "they're wired in series" so I took that at face value.

Have had the same puddle lights installed since 2020 on 2 different model Ys 20’, 24’ no issues.

Yeah, they're definitely linked. The root of the matter is the window goes all the way up when the puddle light is detected as disconnected. Why? I do not know, but I'm wondering if it is to allow clearance in the lower portion of the door for some part of the window regulator mechanism? And if you slam the door closed with the puddle light unhooked, the window will be up, so it could absolutely break the window. So the horror story is very plausible! I suppose an aftermarket light could fail and it would stick the window in to "up" position, but I think it would be more likely that the electric connector retainer clip might not get plugged in tightly due to installation error, and work its way loose. I can see why a light being unplugged would act like it's in series with the window motor. I wish there was more good information on this.
