93 es300 - the cd changer does not open or play...l had a 96 before w/ the same problem...is it a defect in these models or what?

Im sorry if this sounds vauge.

l need more info to answer ur question.
If u have the standard Lexus sound system, then u have a cd changer made by Pioneer.

If u have the upgraded Lexus sound system, then u have a Nakamichi system & the cd changer is made by Panasonic.

l have the Nakamichi system & my changer is in the trunk.
If yours is like mine, there r 2 cables that plug into the changer. One provides the music data, the other cable provides the electricity.

1. Make sure that both r attached.
You cannot plug them into the wrong spot since each connector will only plug into its own spot.

2. Check ur fuse panel, which may be in the engine compartment. The underside of the fuse panel cover has a map to help u find out which device uses which fuse.
There will be a fuse labeled radio or stereo. Make sure that this fuse is not blown. If the radio is working then the CD should work as well.

Good luck.
