The only solutions I see left from your explanation is a short or a bad ECM. Unfortunately there is no easy place to start tracing these wires. Start in the obvious places that may have caused wear on any wiring involved in these circuits. Places where wires come in contact or are likely to come in contact with the metal edges of the firewalls and along the engine areas.

How do i turn on the radio in a ls400 1998

The Nakamichi radio in the 1998 Lexus LS400 is turned on by pressing the large round button on the radio in. This same button also controls the volume by turning it clockwise or anticlockwise. The radio will use the same audio input that it used when it was turned off. The input can be changed using the series of buttons on the right side of the radio, tape, cd, fm, am.

Have a Lexus 1995 sc400. On the stereo the front tweeters work and the subwoofer work but the door speakers and two of the back speakers do not work. What do you think may be the problem? Jeff

Your amplifier located in the right rear trunk area wheel well has IC's transistors etc. that overheat from high volume as well age. I had mine repaired for about a 150.00 in Oklahoma city. Look on ebay for used might be best way to go..
