LS Cigarette Lighter Fix (Tutorial)
#33
Does anyone know the name of this washer, and what it's purpose is? Maybe it is designed to prevent a particular surge from burning out the whole fuse panel? If it is there, it must serve some purpose.

the cigarette lighter mini fuselink is troublesome and redundant, there is a cigarette lighter fuse in the kick panel, I removed the fuselink and put the cigarette lighter socket back together over a year ago and smooth sailing ever since!
just a little ridiculous over-engineering by Toyota, that came back to bite them in this case. If you are mechanically and electrically inclined, then how to re-engineer it becomes obvious once you have it apart!

I don't think it's ridiculous to use the extra heat sensitive part as a fusible link behind the cigarette lighter socket. It is not fully over engineered by Toyota, I must say. But I say it wood be better to use a newer part which returns to conductive again when cooled down.
We circuit designers have to be very careful against the fire hazards. Please remember that the part at the socket is open by the excess heat. It is checking the heat. It's not often the case but there may be some possibility that the cigarette lighter does not pop up although it is heated enough and the current is not stopped. What will happen in a case like that?
The continuously running current generates heat more and more. The accumulated heat may burn the socket or the whole console or even more because the fuse located away from it has no idea to open since the current is not exceeded.
There may be also some people who are not like you and are ignorant enough to cause a fire hazardous problem jiggling the cigarette lighter socket inserting something unusual.

I still say over-engineering, and not engineered using a fail-safe part, as this part is trouble prone. It caused me to be unable to charge my cell phone and therefore unable to communicate in case of a real emergency, and not having a phone is a much higher safety risk than a million to one chance of a car fire in the 12V outlet.
I say over-engineered because I have been driving for almost 40 years, and had dozens of vehicles, and I have never had, nor ever heard of a case of anyone I have ever known having a car fire due to a 12V socket overheating. Not saying that it could never happen, but I suppose lightning could strike the car as well, but I don't see anyone driving around with a lightning arrestor on their car!
To me, the mini fuselink is redundant, on the rare occasion that I have overloaded the circuit concerning the cigarette lighter, the normal cig lighter fuse pops, end of hazard!
I would not mind having the fuselink as an extra safety feature, if it were reliable, but when these cars age, it is not reliable, just troublesome! - left me with a dead phone!

that video definitely pinpoints that little bastard fuselink!
I removed the insulator washer, like he did in the video - my 12V socket has been great ever since!

Rear Lighter Fixed
Thanks Legionofon and everyone else for the tip. My rear cigarette lighter or should I say an external power source is now working. I haven't been able to use the rear outlet for so long. I do not even remember what caused it but it is fixed now.

I have a similar issue that is not quite the same on my 2000 ls400. The circuit that the cigarette lighter is on blows the fuse when the ignition is turned on. I've check for the fabric washer fuse behind the nut at the base of the lighter, there is none there. Anyone have experience with this issue?? Thanks!

check the above post. The video above was immensely helpful (thanks EmpPenguin for posting that!). The fabric washer was there, just not where i thought it would be but virtually the exact same design as the toyota camry in the video. Apparently that fuseable link was causing the short in the circuit and blowing the fuse. Now all seems to be working, including the port in the console. Again, thanks to all who contributed!

As far as I know what is specified is the temperature rating not the current rating. I don't remember the exact value of it but it works to stop the current when the temperature reaches to certain degrees which is a bit below the plastic starts to melt.
Come to think of it, the current is already limited by the fuse which is located closer to the DC source and you don't need to use another one in series with it at near the end but in order to avoid the risk of fire hazards, the device is used. So that is important to exist. That's the way Toyota designs products.

Yeah but I suppose to fix it costs $50 or more for a new unit when that little link is only a .50 cent item if that.
How many other makes of cars use that sort of thing? In the old days if plastic was used it was something like Bakelite that was used and is very heat resistant, I don't think it will melt.
