dead 91 radio
Nothing works - antenna does not go up, display is clear - no clock,
looks like the ignition switch is off. Looking at the FSM section 8, there are interfaces with the CCM and several other systems. Does anybody have a clue where to start looking? The radio fuse in the dash end cap is OK, but I have not looked for the fuse under the dash. Could this mean a dead radio module? |
is it the Bose system?

Check the Bose relay which I think it is under the dash of that year car.
Also check the connector or corrosion for the tuner unit which is behind the passenger seat in the compartment. There is also a ground in the same compartment but is probably not this problem. |
Yes, it's a Bose system.
"Also check the connector or corrosion for the tuner unit which is behind the passenger seat in the compartment." - no tuner unit there in the 91; I think it got put there later when the passenger air bag arrived. |
Sounds like an internal short in the head unit if nothing looks like it's powered up. The radio receiver should be above the passenger side kick panel.
The Bose relay is for the speaker amps themselves. You might try posting the issue in the Audio and Electronics section. Sounds like the best thing is to either remove the head unit and fix or replace or go with an aftermarket system. Contact Dennis at Double D Mods; he's a CF supporting vendor (username is c5 BearsFan) and is very highly regarded when it comes to audio systems. |

One more: hit the SET button and the LED lights but can not set the clock - it stays at 1:00. No other head buttons seem alive. |
Sounds like the CDM.

take the oportunity and improve the sound system
after many years, repairing the unit, and amplifier. at last I removed the bose system was a great system, but now exist better option at very affordabel price. you can install a new unit, single or double size unit. the adapter sells in a lot of places. double size includes video screen and gps,mp3,sd,usb ipod I installed a single unit alpine with usb and ipod ready. I tried 3 configurations. 1 setup 1.- Front 6 1/2 boston acoustic 2 way component 2.- rear 6 1/2 woofers 3.- 4 channel amp 4.- 2 way electronic crossover audiocontrol great accoustic the bass sounds in front 2 setup 1.- Front 6 1/2 boston acoustic 2 way component 2.- rear 6 1/2 speakers 3.- 4 channel amp better overall sound and cheaper 3 setup 1.- Front 6 1/2 boston acoustic 2 way component 2.- rear 6 1/2 speakers 3.- 4 channel amp 4.- 10" woofer in 1 cargo storage side (non abs) 5.- 1 channel amp 6.- audiocontrol epicenter a lt more bass but really dont need it for me the point is that with a new stereo and 4 speakers you will have a better sound quality, mp3. the rear speaker enclosure already exist, front you need to make it, mine in fiberglass |

According to Dr.Don, the power supply in the receiver (CDM?) has failed, and it's on the way to him for repair. That little SOB is a real bear to remove.
