2003 Lexus LS430 Q&A
2003 Lexus LS430 Question: No sound when I turn the key. Lights all work, even the headlights.
Are the lights bright but dim slightly when you turn the ignition key to "start"? Try "jump starting" your car off another car just to help eliminate the battery as being the problem (allow the other car to run for a few minutes and make sure your connections are good). It is likely the starter solenoid on the starter has failed. But I would check for power at the starter when key is in the start position (power should be present on the smaller wire at the starter when the ignition key is in the cranking position only) and check battery power and ground cables are clean (free from corrosion) tight and secure. Starter is not easy to replace in that car, intake manifold needs to be removed. - patrick mannion
