#46 of 55 2004 LS430 Inside Trunk Release by dandydon2

Jul 24, 2010 (9:59 am)

Just recently, my 2004 LS430 dashboard trunk release switch has stopped working. Any suggestions ... fuse, loose wire, etc.? Car is in top shape otherwise, with only 48K miles.
 
Any suggestions will be appreciated.

Probably the first two things to check are a) fuse and b) get a test light, open the trunk with the key, and test for voltage to the trunk lock solenoid when someone else works the dash switch.

Be sure the valet PB isn't depressed.

Bingo, Mr. Shiftright,
 
The problem was exactly as you suggested, I had inadvertently pushed the lockout button. Didn't even realize there was such a button there.
 
Thanks to all for your suggestions.

rest assured that you are admired, wwest, even though not every poster gets the threaded or accreditation right.

Well, console yourself---think of those rare occasions when YOU got credit for my suggestions--LOL!
 
Remember, being a genius is a thankless task -- and yes you can quote me.

This post is 2-1/2 years old, but it is currently relevant to me. Does anybody know how this is resolved? I have the same symptoms.

#55 of 55 Lexus Starting and Electrical Problems by lexusls400

Jan 28, 2013 (12:35 pm)

I have a LS 400 2000. Going well for last 13 years until last month. Starting problems. Dealer changed battery. Did not use for 3 days and car did not start. This time they changed the alternator. OK for 2 weeks. Again did not use for 4 days and car did not start. They said maybe an electrical drain somewhere they cannot figure out. All fuses are good. An independent person verified that the battery and alternator are good. By the way, they also changed a terminal on the battery.
 
Also the electricals on the driver side door do not work such as driver side controls for other door locks, other door glass up/down, side view mirror controls and the alarm. This happened since the battery went down the first time and I had to jump start the car. Dealer says these are unrelated. In any case they feel that there is an electrical drain somewhere and it will cost $ 1500 to diagnose. Not sure if it is worth it, because if I start the car once a day, then it is fine the next day.
 
Regarding the electrical issue in the door, last week, suddently all of these electrical issues were gone, and I thought it was well and good. Again it seemed to not work. This has happened 4-5 times and I have just given up. Can anone make any suggestions. Thanks very much !
