Question about 1991 Cadillac DeVille
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?
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.......
