Unless the switch is sticking in the on position . A relay load circuit contacts may be stuck causing a constant feed drain .

Which three fuse's did you replace ? You should check for B+ voltage on both side's of the fuse . Two little metal tabs on top of the fuse. Voltage on both , fuse is good .
Try radio self-diagnostic mode .
A fluctuating AC voltage audio signal is sent to the speakers directly from the audio unit to reproduce sound. The audio unit has a self-diagnostic mode that can be entered by pressing preset buttons 3 and 6 simultaneously.

1. If the concern is not visually evident, proceed to the Speaker Walk-Around Test and the Audio Unit Self-Diagnostic Mode.

Speaker Walk-Around Test (Except Premium CD6)
NOTE: To enter the speaker walk-around test or audio unit self-diagnostic mode, the audio unit must be turned on and in the radio tuner mode (AM/FM).

1. To enter the speaker walk-around test, simultaneously press the audio unit preset buttons 3 and 6.

1. The speaker walk-around test stops at each speaker and applies sound to each speaker for about 1-2 seconds. Each speaker is tested and displayed on the audio unit in the following sequence: RF, LF, LR, RR and SUBWOOFER.

1. To exit the speaker walk-around test, turn the ignition switch off, turn the audio unit off, or press preset button 1 for diagnostics (DIA).

Audio Unit Self-Diagnostic Mode (Except Premium CD6)
NOTE: To enter the speaker walk-around test or audio unit self-diagnostic mode, the audio unit must be turned on and in radio tuner mode (AM/FM).

1. To enter the following tests, press the desired preset button while in the speaker walk-around test or while in the audio unit self-diagnostic mode.

1. To exit the audio unit self-diagnostic mode, turn the ignition switch or the audio unit off.

1. If the concern remains and the fault is not detected, GO to Symptom Chart to continue diagnostics.

1. The self-diagnostic mode has 6 manual tests available:
   • Preset button 1 = ENTER DIAGNOSTICS. This test enters diagnostics from the speaker walk-around test. Metrics are available with SEL and ON buttons indicating time played in AM/FM, media, number of buttons pressed, etc.
   • Preset button 2 = EEPROM BLOCK STATUS. This test shows the validity of memory to calibrate the clock, and seek sensitivity.
   • Preset button 3 = EXIT DIAGNOSTICS.
   • Preset button 4 = Software configuration level. This test queries each radio system controller for its software configuration level.
   • Preset button 5 = DISPLAY TEST. This test lights all the display segments for five seconds and then turns all segments off.
   • Preset button 6 = RAM CONTENTS READOUT. To enter these tests, press preset button 1 while in the speaker walk-around test, then the desired preset button.

1. To exit the self-diagnostic mode, turn the audio unit or the ignition switch off.

Hello my name is Ben. I have had 2 of these cars and they both worked the same. Once you load the cartridge with your CDs and insert the cartridge into changer and close that little door on the changer the rest is automatic. On the dash you will see two buttons to the left of the radio display. One says TAPE AUX. That is the button that switches from radio to the CD changer. Push the TAPE AUX button and the CD changer will play whichever CD is selected. The PREV button if pressed during the first 8 seconds of a song will go to the previous song, if PREV is pressed after 8 seconds it will go to the beginning of the song. The PROG button will go to the next CD. The NEXT button will go to the next song on the CD you are playing. The REV and FWD allow you to quickly move within a song, either forward or backward. If you have any other questions, just ask, I have the owners manual readily available. I know it should be in the car, LOL

you can take it to your mechanic. you might have to replace the entire radio set though

Not many I've seen do, I guess because if you delete it, what does it delete to?

1988 CADI Eldorado Biarritz, 4.5 liter v8: locked keys in car, called locksmith he put inflatable air bags in door to stretch 4 space to slide his crooked metal stick in and reach pull the handles, push electric door lock button/switch and manually but doors would not open. He than pulled the keys out of ignition and out the crack. Guess what, both doors sounded like they unlocked with the key but would not open. Is there some kind of anti theft protection that kicks in when you mess the doors and locks inside? Help, I have my keys but car doors will not open. Did stretching or forcing doors open a bit with these airbags possible cause damage?

Holding the button is supposed to work. This from owner's manual: PRESETTING A STATION:

1. Tune in the desired station.
2. Push one of the station selector buttons (1-6) and hold it until a beep is heard. This sets the station to the button and the button number (1-6) appears on the display.

Each button can store one AM station and two FM stations. To change the preset station to a different one, follow the same procedure. The preset station memory is cancelled when the power source is interrupted by battery disconnection or a blown fuse.
