Ls430 Cannot Start, Electrical Short?

LS430 / 2005 has been running well, yet cannot start up this morning without any warning sign, only hear the click sound,

all the dash board lights are on, signal lights and emergency light are working,

driver side window is not functioning yet all the passenger side window works fine,

cannot adjust steering wheel position,

cannot horn or turn on head light;

I did jump start, but still cannot start the engine, so it is not the battery problem, feels there are something wrong with the electrical system, any suggestion? Thanks in advance.

Hi,

Could be a fuse or a circuit breaker, on the LS400 there is an engine compartment fuse box and another behind the drivers footwell kick panel,do you not have an owners manual as all the details should be in there.

What do you mean click sound? Do you mean the starter engages but just doesn't turn over the engine? Or is it the fast clicking sound that comes with a dead battery where it is rapid back to back clicks? Do any lights dim when you engage starter or does starter never engage.

If it is just starter won't turn over engine then I'd check electrical connections at battery and other end of the heavy wires (red goes to starter motor, black goes to frame ground) looking for loose connections and/or corrosion.

If the starter isn't even engaging maybe you've tripped the anti theft system. Id' just disconnect negative battery terminal for 10 minutes then reconnect and try again.
