Question about 1991 Cadillac DeVille

1 Answer

Instrument cluster went blank

The digital instrument cluster for fuel data and a/c info went blank. I've checked all fuses both under dash and hood and looked for damaged or burnt wires under dash and to the headlight switch and all looks okay. What would you suggest?

    1992 Cadillac DeVille - I smelled something burning and all the instrument lights went out. Found that the board in the fuel data center was the problem. Well, I replaced it and still no lights or no blower for a/c.

    I have this same problem and was wondering if I replaced the entire instrument cluster would this fix the problem ? Would my A/C and fuel gauge work again ?

I am currently working on my 92 Deville with the same problem. I was driving along, and smelled what I felt was a smoking printed circuit board. I looked down, and the digital fuel data center and climate control panel were dark.

I have the factory shop manual, and with the aid of a meter and the manual, I traced the problem to a bad BCM. The 16v supply coming from the BCM was gone. Opened up the BCM and found an overheated transistor. I also removed the fuel data center and the Climate control panel. The fuel data center panel did not smell good. I found a shorted capacitor on the Fuel data center circuit board. I am replacing the capacitor, and will be picking up a used BCM at the boneyard tomorrow. I might also have an overheated wire in a cable that might have to be replaced. I have not gotten that far in the troubleshooting yet.

Good luck with your problem.......

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the concern is not visually evident, connect the diagnostic tool to the data link connector and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
    • check that the program card or disk is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
    • SCP or UBP circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 .
    • No response/not equipped for the instrument cluster, Go To Pinpoint Test G . For vehicle security module, refer to Section 418-00 ; for anti-lock brake system (ABS), refer to Section 206-09 ; for restraint control module, refer to Section 501-20B .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the instrument cluster.
  1. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index or the Powertrain Control Module (PCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics. For all other DTCs, refer to Section 418-00 .
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue diagnostics.
Instrument Cluster Self-Diagnostic Mode
To enter the instrument cluster self diagnostic mode with the engine off, press and hold the odometer reset button (base cluster) or the message center reset button (message center cluster). Turn the key to the RUN position and hold until the display indicates tESt (base cluster) or TEST (message center cluster) usually within three to five seconds. Depress the reset button once to advance through each stage of the self-test.
To exit the instrument cluster self-test mode, turn the ignition to the OFF position. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.

'95 Lincoln town car. Husband was driving uphill and the digital dash suddenly went dark. Radio is working and a/c is not. Exterior light still working and so are interior lights besides the dash


Could be a bad wire possibly chaffing or grounding out to to another wire or frame. Check your fuses. You may want to pull the dash out and check that wiring as well

Dash lights dont work on my 97 blazer


All lights, or just your illumination lights? Illumination: bulbs need replacing. All lights; SERIOUS problem. There is a dash panel fuse on car. check that. Has anyone done any work recently under dash( like installing a radio)? May be they accidentally pulled a connector loose behind dash. Need to pull your instrument cluster to check that. Usually two big connectors with lots of wires going to back of instrument cluster. If no power at all with key on: check under hood at power distribution center for a main big fuse out.

Desparately looking for the fuse box in my wife 2002 caravan. nI can only find the one under the hood in the engine.... dash lights went out and can't find the fuse


There is no fuse specifically for the instrument cluster illumination lights. They are controlled by the BCM.

Is it only the instrument cluster that has no illumination or do the rest of the items like the radio and heat controls also loose there illumination lighting?

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).
