Lexus Rat by oregonboy

A lady-friend of mine has a mid-to-late 90s Lexus GS300, (I think that is the model: 6-cyl. RWD), that was exhibiting strange behavior. She took it to the dealer, who informed her that a rodent had been dining on the main cable runs between the transmission and the engine. (Perhaps the engine control computer. I got this all second-hand, over the phone, while she was driving.... Yeah, I know, stereotypical female Lexus owner).
 
The Lexus dealer will replace the cable for $4,000 plus $1,400 in labor. I guess it must be made with gold wire.
 
She then took it to an independent shop that works on Lexus and asked if the cable could be repaired. They suggested that she try an "electrical shop", but that there may be a risk of damaging the tranny.
 
She is located in the Seattle-Tacoma area, so there should be lots of "resources" available to her.
 
Thoughts, ideas, suggestions?
 
James

Well a shop specializing in Japanese cars might tackle it but it's a rather scary job for a mechanic, since one could end up being "married" to the car for life. This is why jobs like this are usually overbid. Combacks are almost expected. The dealer is obviously going to replace the entire sub-harness and not mess around with any splicing or repairs; whereas an indie shop might take a chance on repairing only what the alleged rodent chewed through, with the understanding that there are no guarantees.
 
Another issue is electrical fire and the liabilities that go with that. So the dealer is playing it safe by repairing the entire subharness, from one connector to the next. This is no doubt a tedious job in itself and I would imagine the harness is not cheap and must be special ordered.
 
You can shop it around but be careful what you wish for, you may get it.

Headlight not working ... Crackling High Beam by email4kh
Oct 22, 2008 (1:26 pm)

2000 Nissan Quest . My driver side headlight isn't working. IT'S NOT THE LAMP/BULB. I've checked the underhood relays and all the fuses. The high beams work, but I've noticed that when I move the switch stem around, there's a crackling sound coming from behind the CD changer (near the floorboard behind the middle of the dash). Anybody familiar with this? Is it more likely the high beam switch or whatever's making the noise in the dash? Thanks!!

I think you're going to need to find/buy/subscribe to a set of factory electrical schematics. Typically in that circuit on that car is the stalk switch, a set of relays, a set of DRL (daytime running light, if your vehicle has them) relays, and sometimes a computer control like body control module.....and of course the bulbs.
 
You might try www.nissanhelp.com, sometimes they have downloadable manuals.
 
If you can find a set of electrical schematics in electronic format, I'll help you with the trouble shooting if you need/want.

Actually, I just went to the site, and they have the electrical schematics for your vehicle you can download. There is aspecifically a section for headlights, which includes a diagnostic section based on your symptoms.
 
You should have everything you need to isolate and fix your problem.

'99 Concorde from HELL!!! by grandmascar

I have had problems with the interior lights flashing, then I couldn't turn them off, so I took out all the bulbs so my battery wouldn't be drained. Yesterday I was driving and all of a sudden lost power, including my steering. I coasted to the side of the road. My headlights and dashboard still worked. (I do have plenty of gas in tank.) I waited a minute or so, then restarted the car. I drove it home but now I don't know what to do. Why would the car lose power while driving? This is the worst piece of crap car I have ever owned!

Well, in the GM world, especially Cadillac of about this age, there is a problem with Crank Position Sensors (Cads have two). When they have a problem, it will totally kill the motor. And many times the car will restart in a short time. And, it does not set any check engine code/s.
 
But, no idea if this your problem.
 
Oh, and a battery cable that failed will also shut the car down.
