My rear defroster wire was all burned up and it's relay was unplugged when I bought my Millenia. I slapped a new relay on it and it started killing my battery while the car was parked. So I unplugged it and my car stopped dying. I don't know what the hell could have caused it to burned. Is it dying because a burned wire is hooked up to power?

So I cut the whole harness off that the burned wire was a part of and spliced in a new harness and relay. Will this fix the problem or will the new one burn as well? I traced the burned wire all the way up to the back window and it was not pinched anywhere.

Here is what I replaced:

If the image is a accurate depiction of how you removed the PJ. Then, the wiring harness was partly the problem.

If the vehicles battery is dying from simply plugging in the existing PJ, then the cicuit is active / live.

That could have been caused by the faulty relay, and the PJ shorting to ground against the frame, or other metal partition.

How is the vehicle now, since the installation of the new relay, and wiring harness?

You have to remember that electrical wiring burns up due to the following common reasons.

1. Wire diameter is too small for the length / run.

2. Current draw is too high.

3. The insulation on the cable is not sufficient to the ambient temperature environment.

4. Schaffing / open insulation causes arching to deteriate the surrounding insulation, thus causing burning.

Remember, if and when a wiring harness burns inside, the overall diameter of the cable is smaller, and is also fused causing more resistance and also more current draw on the cicuit.

Well, being that this is factory wiring, I'm sure the wiring length and insulation is pretty sufficient. Otherwise, there would probably be a major recall on all Millenias in my cars production period.

Yeah, the battery was dying when I plugged the burned harness (pictured above) into a new relay. It would be dead after like 2 hours. It only happened at work when I went to move the car for lunch. For some strange reason, it never died overnight though. It would start up perfectly in the morning, then I'd drive to work and park, and it would be dead by lunch. So I unplugged the harness from the relay and it never happened again. It's been about 4 months now.

So I cut that burned harness off and replaced it with a new, exact same one and a new relay. I let it sit for about 5 hours before I tried to start it. I parked it at about 6:30 p.m.. Then I went to see Troy at 9:00 and got home at 12:30 a.m. It started right up when I got home from the movies.

Hopefully I fixed it, but I still don't know what caused it. I couldn't find any chaffing of that wire. We'll see when lunch time rolls around tomorrow.

Auto makers in general do not make *issue* general recall's unless the death / loss ratio has been met.

Chrysler's Durango & Dakotas are a case in point. The upper ball joint(s) has been proven to wear prematurly, and thus causing the wheel to fall off.

There have been 4 national TV broadcasts about this fault, and still the maker refuses to issue a recall.

The other aspect is that the owner must also submit the fault(s) to the dealers, so as the same information may be obtained and testing and varification to be validated.

Most automakers use their TSB's to alert the dealers to potential hazards etc. But do not make it a manditory *have all* TSB's to be inspected on all vehicles and service to be performed.

Just another side of the coin for you to see.
