lunavic50 Posted February 4, 2008 Share Posted February 4, 2008 I have a 93 lexus ls 400 well heres whats strange. My cluster odometer , temp , and fuel gauge works fine. The rpm and the speedometer dont reg right. When Im going 50 It says Im doing 30. Ok now when I have my lights on the reverse light lights up in the cluster and the car won get out of second gear. When I turn my lights off... its fine,, Ive pulled the fuses for gauge and panel to see if the cluster was the prob but still the same prob.. Has anyone ever heard of such a problem any suggestions would greatly be appreciated thank you Quote Link to comment Share on other sites More sharing options...

90LS400Lexus Posted February 5, 2008 Share Posted February 5, 2008 That particular problem sounds like something that may be connected to the trunk hinge wiring loom issue. Well known problem.

I agree with the trunk wiring problem, Lexus didn't make the wires long enough and they wear down and short out. Very common problem with the early ls.

Yes, Use the search function on top of the forums. There is plenty of info on the subject, It hasn't been discussed lately so go back a ways.

dpellet Posted March 26, 2008 Share Posted March 26, 2008 Check drivers side hinge in trunk, pull the black cover and the wire harness out and take off the tape that is around it, if this is the problem you will notice that wires have seperated, it's a relatively easy fix just re-attach the wires based on colours, hope this helps as I did mine and it corrected all the weird issues, if memory serves me right the were 4 broken wires.
