Question about Cadillac DeVille

1 Answer

No Sound From Speakers

1972 Cadillac AM/FM Stereo Radio (no 8-track!). I have zero sound from my speakers, but I can faintly hear the radio sounds coming from the head unit itself. The radio powers up. After turning it on and getting nothing but silence several times, one time the speakers did make a loud sound when I turned it on, then silent again. The signal-seeking function is working, it can find stations that come in, so I believe the antenna is hooked up and working. Plus, if the antenna was the only problem I would still expect to hear static from the speakers. I believe this head unit has an internal amp. My service manual makes no mention of an external amp (unlike a '69 Caddy I have). I have tried hooking up a new 6X9 in the rear. Another thing I am puzzled by is the rear 6X9s are apparently only supposed to have one wire running to each, no ground wire? How can this be possible? Thanks, Brian.

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?

Radio have power but no sound to car stero speaker what maybe the problem


Hi James, Im AL the owner of Big As Auto Repair.

James, Cadillac stereo systems have an amplifier and usually when there is no sound from the speakers its because either the fuse to the amp is blown OR the amp itself is bad. Hope this helps and please visit my auto-repair-website here: http://www.bigasautorepair.com/

I have a 1995 gmc jimmy stereo sound doesnt work


Are you sure you are listening to a stereo program (e.g. FM radio or CD/Tape)? Have you tried adjusting the fade and balance controls? If sound is not coming out of all speakers, you will probably have to replace the radio.

Radio power is on but no sound coming from speakers/radio on 2005 Acura MDX. Sound works with CD's


Turn on the radio and increase the volume if you can hear a hiss through the speakers, chance is the aerial/antenna connection is not hooked up correctly. Another way to check is try tuning to an AM station if you get a signal on AM but not FM then it is The antenna. You may have to remove the radio to get at the connection.

Bose radio comes on but no sound in my 2004 chevy avalanche.Sometimes even with radio off you hear a popping sound come from speakers. thanks


First Visually check all your fuses. Does rig have amp for stereo by any chance? It sounds like amp is bad and/or fuse is blown. Amp is wired between radio and speakers, and a shorted amp would make crackling in speakers when radio is OFF
