Check that there are speakers! stupid as it sounds, sometimes there are just covers with holes behind...

If there are speakers trace the wiring through to the source make sure it has been conected both ends...

Or check the balance & fader on the set.

Table 1: Radio Features
Table 2: Cassette Features
Table 3: Compact Disc Features
Table 4: XM Advisory Messages
The radio receives power from the RADIO fuse in the junction block-right I/P. Ground is provided via G201 and G202. The radio is enabled/disabled by class 2 messages from the body control module (BCM). The radio routes audio signals from the digital radio receiver or the vehicle communication interface module (VCIM) to the speakers and/or amplifier when directed by class 2 messages.
The Entertainment System on this vehicle is configured with an AM/FM stereo radio with the radio data system (RDS) and either a cassette player or a CD player or both. CD and cassette. The uplevel system provides the customer with extended range speakers and an audio amplifier. Satellite digital radio (U2K) is available with uplevel systems.
The following list shows the radios available for this vehicle:
• Radio (ULO) - AM/FM Stereo, Cassette with RDS
• Radio (UNO) - AM/FM Stereo, CD and RDS
• Radio (UPO) - AM/FM Stereo, Cassette with CD and RDS .The complexity of the radio systems on these vehicle is mind blowing .

Your best bet take it to a GM dealer , has features you are unawear of .
DTC B1025, B1035, B1045, or B1055
When the radio is powered up, the radio supplies low level audio signals to the speakers. If the vehicle is equipped with an audio amplifier, the amplifier will boost the signal sent to the speakers.
DTC B1025 Audio Output Circuit
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, monitor the DTC Information for DTC B1025.
Does the scan tool indicate that DTC B1025 is current?

04 Infiniti sedan w/ factory Bose. Front speakers are not working (no sound at all) and I adjusted fade all the way both ways. Back speakers are fine. What's up?

If the rear speakers are fine, perhaps I can narrow this down. Fuses must be OK. Steering wheel audio controls connect to the audio unit which has a preamp function. The W/BK outputs connect to the left front inputs of the Bose speaker amplifier; the GRN/RED outputs connect to the right front inputs. Your ear test confirms the front door speakers are not working, therefore there is no front door output from the amplifier. The amplifier stages for the front doors may not be working or no front door amplifier input is being received from the audio unit. The fader and balance controls do not show on the diagram so must be on the front panel. They could be defective. There is a remote possibility of broken/disconnected wires

I have a 1999 Cadillac DeVille Concours with an AM/FM/Cassette/CD/RDS Radio. The AM works fine, the FM does not, screen shows digital info(stations like 99.3, etc) but no sound. RDS does not function at...

Hi there,

Well there's lots of possible reasons. The FM receiver portion of the radio is separate from the AM Band receiver, pre-amp, and amplifier sections of the radio. The FM receiver may have simply failed, as well as the CD player portion of the radio. Your car FM needs repair, you need a multimeter to check it or take it to a repair person. Please post further comments for further help or information......

Good Luck!!
