99lsguy Posted March 2, 2004 Posted March 2, 2004 Most guys will go to Autozone to get the codes read.....if you think it's drivable? They say it's free! Post the codes and you'll find pinpoint help. Good luck!
AlmightyLexus Posted March 2, 2004 Author Posted March 2, 2004 all right thanks man i really appreciate your help
1990LS400 Posted March 2, 2004 Posted March 2, 2004 Here we go again! It sounds like still another case of a broken wire - probably the "white with black stripe" one - in the left trunk hinge. Try this link or do a search on "hinge" http://us.lexusownersclub.com/forums/index...c=4726&hl=hinge One of the last occurances of this problem was reported by member "Troubleshooter". There used to be a lot more posts on this problem but they were lost in last years server crash. I had this exact same problem last year and solved it by splicing in a short piece of wire. If this is the problem, make sure you solder in the splice or use good connectors. It is amazing that this one wire in the hinge is too short in so many wire harnesses. Good luck! Jim
AlmightyLexus Posted March 3, 2004 Author Posted March 3, 2004 that was it! thanks fellas i really appreciate it
99lsguy Posted March 3, 2004 Posted March 3, 2004 that was it! thanks fellas i really appreciate it Are you guys saying the this "wire" fixes the Jerk in the Transmission...... I can see how it fixes the Dash Lights..... So a malfunction of an electrical "idiot light" (nothing personal to anyone, I mean that) causes the transmission to go haywire?????????????????????????????????? I need an explantion..................... 99
1990LS400 Posted March 3, 2004 Posted March 3, 2004 Hey 99! I do not know the details of why that trunk hinge wire affects drivability so severely. Maybe the transmission falsely senses that the brake is on when the hinge wire breaks. When mine broke on a Saturday afternoon last summer, the car bucked so badly I had it towed from a parking lot at 119th & Metcalf. I thought the transmission was fried. I finally got it home, searched the Internet and found this forum. I was amazed when I found the answer to the problem on this forum in a couple of minutes and had the problem fixed within an hour. It is unfortunate that so much forum history was lost when the server crashed last year -- there was so much valuable information that could be searched. Always great to see your posts! See you sometime soon. Jim

And it was a great stretch of posts! don't worry, I've got this baby "cut n pasted" to a Word file now! hehe,, I've got lots of them on MSWord for backup Great troubleshoot! Maybe some BBQ ribs next week........................................... :D 99
VBdenny Posted March 4, 2004 Posted March 4, 2004 LS400 (Jim) knows his stuff. It does seem unusal for a broken wire in the trunk to cause such a problem, but I have seen it reported far to many times to disagree. If anyone needs it, I have a transcript of the original post. Should be a very cheap, quick fix. Denny (my 500th post)
VBdenny Posted March 4, 2004 Posted March 4, 2004 Even got an extra square out of that one. Kind of like the old days huh.
