#47 of 82 keyless entry problem solved
Nov 23, 2009 (4:04 pm)
Ladies and Gentlemen
The keyless entry problem in my 2004 LS 430 with 56,000 miles on it, has been solved by Burdick Lexus in Syracuse,N.Y. These people investigated the problem and found two major components at fault, and they only had my car for a week. The first component was the Theft computer assy ($892) and the second was the Reciever door control unit in the trunk ($754), along with labor ($1,100) for a grand total of $2,746 to repair my LS430. The car is working like it should now and is enjoyable to drive again. When I first reported this problem to the Lexus Corporation, asking for some help in paying for some of this, because Dorschel Lexus in Rochester, N.Y. had no clue what was wrong it and didn't even want to try to fix it, and that's after they had my car for two months, Dorschel did offer some lame suggestions that I just live with it, or they can install an aftermarket remote to lock and unlock the doors on my $65,000 Lexus, for only $200. Lexus Corp thanked me for bringing this problem to their attention and informed me that they have sent this issue to the Lexus Headquarters in California, so that they can make a better product. How do you make a better product without the solution to the problem. Well now, thanks to me for paying for their research and development on this problem, they now have the answer. Lexus Corporation dropped the ball on this issue as far as I am concerned. It's too bad that I couldn't sell them the solution to their problem.
On a very bright note though, for people in Upstate New York. Burdick is an outstanding dealership and they are huge in automobiles not just Lexus. I personally would like to test drive one of their BMW's and they also have Hummer along with too many more manufacturers to mention.
I thought that anyone that has seen the keyless entry problem that I posted might be curious about the solution to the problem. Well here it is, so if your car has the same problem that mine did, it will cost you a smooth $2,800 to fix and don't count on Lexus Corporation for anything. I should state that my car is out of warranty as the Lexus Representative pointed out to me several times and they did not have to do anything toward helping with the cost of this rare component failure. I'm fine with that, I don't have to purchase another $65,000 Lexus either and neither does anyone else in this country.
Have a Great Day
#48 of 82 1990 Lexus LS 400 Electrical problems
Feb 13, 2010 (7:49 pm)
I have read postings on various websites that are similar to my problem, but not quite like mines. My interior power will not work at all! Nothing on the inside works (no heat, radio, dash, seats, etc.) nor will my head and tail lights work. I was told I had an electrical problem (which as not been diagnosed by an electrical technician) The vehicle drives fine, but I can not use any electrical devices for the car. I was told the problem is draining the alternator, which I just had one replaced. I did notice that if I turn on the hazard lights, I can see it blinking on the dash and it works outside of the vehicle as well. I tried to turn on the headlights, but they did not work, but I could see where I tried to put the lights on high beams.
If anyone has experienced this problem, please advise!!

This mirror is not adjusting from the dash controls although it will fold in or out. Is this problem common and/or fixable w/o buying a new replacement mirror?

Blown fuse or failed relay.
Most likely the lighting system "integration" relay assembly/module mounted in the dash panel approximately above the driver's left knee.
Check to see if the "flash to pass" headlight function works and if so the integration relay has failed.

I had a similar problem on my 92 LS 400 where it wouldn't go faster than 30 mph at night with the headlights on and the engine over-revs and when I stepped on the brakes, the instrument panel dims out.
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!

#54 of 82 Front lighter fuse problem
Jul 27, 2010 (1:50 pm)
I have a 2001 Lexus LS 430 -just went on a road trip- I was using a GPs- plugged-into the front lighter -after several hours of driving I noticed the Low battery signal on the GPS come on-clearly the GPS wasn't getting power to it to re-charge. I figured it might be a fuse so I stopped at an auto parts store and replaced with a 15 amp as directed by the manual. After several hours
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!
