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.

- If the concern is visually evident, GO to Symptom Chart .
- 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).
- To enter the speaker walk-around test, simultaneously press the audio unit preset buttons 3 and 6.
- 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.
- 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).
- 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.
- To exit the audio unit self-diagnostic mode, turn the ignition switch or the audio unit off.
- If the concern remains and the fault is not detected, GO to Symptom Chart to continue diagnostics.
- 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.
- To exit the self-diagnostic mode, turn the audio unit or the ignition switch off.
- If the concern remains and the fault is not detected, GO to Symptom Chart to continue diagnostics.
