but if I turn the headlights off, it would speed up to normal speed.
I took it in and they found that the bundle of electrical wires that in the trunk next to the left hinge of the trunk were shorted out from over the years of opening and closing the trunk; and the hinge catching that bundle of wires and cutting into them.
They replaced several of the wires and now the car runs normally!
it blew again, I replaced it again and finished my journey so it is an intermittant short. Do I need a special Lexus fuse or does anybody have any idea how to fix this? I'm killing my back each time I contort my body to replace it! Thanks!
Your message is a little confusing. The GPS first indicated that the battery was low, so you replaced a fuse. Then you said "it blew again". Did the fuse blow out the first time or did you just assume it had?
I had a similar experience with my 2004 LS430, in that the GPS kept saying it was low on power. Turned out the problem was that my car battery was failing. When I replaced that, the GPS problem went away.

Thanks for your reply. The fuse had blown and then blew again after a couple of hours.I replaced the fuse both times and it is currently working and charging-However I was hoping to not do a repeat performance of constantly replacing the fuse. I was on a 7.5 hr road trip today however! May be I should have the battery checked out- altho it is about 1.5 years old- I'm in FL. and the heat kills batteries!
Maybe that is getting ready to go too!
Depending on how your LS430 was ordered, there may be a second cigar outlet in the back seat, just below the front seat center armrest. If it is on a separate circuit, you could at least keep the GPS operational while you are tracking down the short.

I'd consider adding an auxiliary 12V outlet from a kit you can buy, and installing it perhaps in the glovebox. I'm sure a radio shop could do this for you for not a lot of $$$.
is not on the same circuit and that will work. I really appreciate your input- it helps clarify the problem and challenges!
No, not really.
It is most commonly the plug in adapters that short out, are shorted out, and when you plug them in the fuse blows. If the outlet fuse blows then the first thing to do is disassemble and check the adapter that you last used.
But the lighter outlets do have two "protective" devices, the fuse that we all know about, and the "fusible link" integrated into the base of the light outlet itsself. This is simply a short lead solder link that will melt away and open the circuit if for some reason the lighter is held down long enough that the heat would otherwise be a danger.
That's not what I have experienced, noted, over the years. In my expereince it has virtually always been a poorly designed/built plug-in adapter that shorts the outlet power and blows the fuse, or worse.
I just ran into this problem on my 2005 ls430. it has only 41000 mi. I wanted to know what is it that they did on your car to charge such an outrageous amont ($2800) . non of my keyless devices work anymore. did they change an entire control board, one microchip, switch , or what.
thanks

At that point, I go elsewhere, or get a new Lexus. So far, mostly the latter.
Any safe mileage above 90K? What would I expect to pay?
Bought new, really like this car.
In '92 valve belt drive was a fairly new thing so the 90,000 mile "range" was more of a guess, now proven wrong, than otherwise.
Where I live in CALIF the total would come out to around $900 out the door. You'd have to add a bit more if you want to replace the timing belt tensioner, which isn't a bad idea.
If you're planning to keep the car, I'd plan to do it at 90K as specified, as the consequences of the belt breaking are somewhat catastrophic.
With a "cheap" car I would expect the use of sub-standard, in comparison, components.
So I would never "treat" a cheap car like a Lexus.
Lexus is now going back to timing chains not due to the short life of timing belts but due to the extreme willingness of their dealers to RIP-OFF the customers with SCARE stories such as above.
