Jim,

I've been trying to resolve a power issue with the fog lights on my 92 ls400. I tested the light conducters and fouond no power, I then tested the fuse that's under in the cluster pannel and theres power but not circulating through to the lights. Is there a breaker or a wire that this particular model suffers from being replaced or something? I appreciate it if you can point me to the right direction.

Thank you

Sorry, been too busy with work to check this forum. I had a similar problem with the fog lights on my 90 LS during the last few years I owned it (sold it in 2003). The repair shop that fixed the fog lights about once each year indicated that the problem was caused by corrosion. Problem is ... I never asked exactly where the corrosion was. They polished it off every so often and got the fog lights working again. I think I was told that a new "fuse block" of some sort would eventually be required to fix the problem but I don't know which one. I'm guessing that the current owner of my 90 LS has solved the problem since he fixed other odd problems. I'll try to ask "Tobywan" if he doesn't see this thread and reply.

Thanks for your reply, I actually found the problem. I was not aware that there was a separate switch for fog lights. Thanks

When you refer to the white wire in the pack, are you refering to the wires inside the trunk hinge? I ask because my 1992 LS is doing the same thing when I apply the brake the reverse light comes on. I would gladly appreciate it if you could point me to right direction.

Thank you

The wire harness is not "inside" the trunk hinge but are attached to the left trunk hinge and flex each time the trunk lid is opened and closed. Unwrap the insulating tape from the wires at the left trunk hinge and flex each wire to determine if wire cores are broken. The wire insulation may not be broken but the wire cores inside the insulation can be completely separated or barely making contact. Splice in new short lengths of wire -- soldering the connections are best but not absolutely necessary. The wires may break again in a few years and you may need to repeat the process.

sounds like a pressure switch issue, no clue where or how to fix it.

Neal,

I have been groing through the same with my 92 Ls400 and was wondering if you were finally able to find out what was the problem causing the suspension to act this way. Could you give me some pointers?

Thank you

Got that right. After two repairs, I configured the wires outside of the hinge so they didn't bend so much opening and closing the trunk. I spliced in a little extra on a couple that looked like they had been bent a lot. I taped it all up using a continious piece of tape unlike how the original was taped (which was challenging at best) and it has worked fine ever since. My suggestion is not to try and put it back in it's original location, leave the wires outside the hinge indent. You can't even see it when standing behind the car.

Thanks guys, I found it, repared it, and were back to normal. This is a wonderful website, I thank God for the person or persons responsable for creating it.

When the "R" light comes on when you brake, it means the white wire in the pack in the left trunk hinge, is broken. Happens all the time on these. I read somewhere that Lexus made the wire too short but I suspect time and repeated flexing is the main issue. I spliced in a small section and fixed everything. Keep in mind that when that wire is broken, the shift pattern is severly compromised. As far as the trunk issue, that IS your biggest problem. Maybe more than one wire broke and the other one locks you out of the trunk so you are forced to go to a dealer. They wouldn't be that sly, would they?
