Really?

So when my friends 1998 LS400 Alternator was failing, and then finally failed while I just happened to be driving it....the battery was discharged...then I imagined that first the radio went out, then the climate control....and finally the instrument cluster?

Then a minute later the engine cut out....

All conjecture?

 

Yoda, the alternator is fine. The search continues

 

Funny thing, I would have stopped searching by now. I would just run new wires from the fuse box (where you say you still have power) up to the AC and radio. But make sure you have an inline fuse on new wires. Maybe some wires actually burnt when you heard the pop. Did you trace the wires back from the AC/stereo back to the fuse box to see how they look? It's gotta be somewhere in that last 3 feet if you still have the power coming out of the fuse box.

 

I did as you said, I now have power to the AC controls, but they do not do anything, every buttons acts as it should but no response from the ac.

 

Wow. Well, maybe the pop you heard was from inside the AC unit. The electronics are above my pay grade and knowledge. All I can say now is good luck and hope ya get it soon.

 

FINALLY. So after installing a new compressor i immediately heard a fuse pop..... yes battery wasnt disconnected, youd think id learn... but anyways i went under the dash and radio fuse no 2 blew, i had a 30 amp there for whatever reason, i may have done that but i don't remember, after replacing fuse everything kicked back in....


Thread closed.

 

Wow a fuse? Didn't you say you checked "everything"? What dealer do you work at? In the future when something like this happens.....change the fuse for whatever isn't working first, even if you look at it and it looks good. Lesson learned, glad ya got it fixed.

 

the fuse was good until i plugged in a new compressor, I had checked every fuse on the whole car prior even though it wasn't burnt out at the time.

 

Gotcha. It just seems weird that you say it was good before, stuff didn't work, and now with a different "good" fuse everything works. The mysteries of auto ownership.
At least now ya got heat/AC.
