This is defenetly the BCM, I had a 1990 with all of the same problems. Buy a rebuilt and install it behind the clove box. Remember that you must install you memory prom into the new unit as they don't come with any in them (it is what is memorizing your miles driven.) You will get off pretty easy on this one as they are available and not too expensive.

If its a digital dash not that this sounds good but smack the dash right in front of the steering wheel a few times and if it clears up or makes it do other things it needs a new instrument cluster.

1985 Cadillac Fleetwood d elegant installing a aftermarket radio lost the lights in the electronic climate control and fuel gauge.. fuse is still good where to look next


next I would check wires going to fuel gauge and climate control .more than likely when you took out radio the wiring might had come loose. if still no lights you can put back old radio and see if you have lights. wiring might be part of all three.then it might be possible those bulbs for fuel gauge and climate control might just have burned out especially being an 85

Cadillac deville 89 fuel data center and climate control arent working.


Hello Belinda Reid,

Nice car...
(sorry... I'm sure you are not in the mood right now)...

There are CADILLAC Clubs across this country
(lovers, admirers, professionals & amateurs)...

I recommend for future issues you seriously consider
looking into joining... The wealth of information is
really quite EXCELLENT... or buying your own set of
FACTORY WORKSHOP REPAIR MANUALS.

For these issues... (I doubt they are related)
Starting with a GREAT CIRCUIT DIAGRAM
would be the best approach...

I PREFER PROFESSIONAL GRADE FACTORY
repair manuals ... but FREE circuit drawings & your 22 TECHNICAL Service Bulletins (TSBs) can be found
on BBB Industries website
(registration is required... these are real documents)
BBB Industries Premium Alternators Starters Power Steering Products

In the 1989 Deville (an issue shared issue w/Eldorado) ...
I did find a TSB on "BLANK DISPLAY" ... Ironically the
TSB page was also blank (GM humor ..
(I presume)).

The FUEL GAGE seems to be a popular part...
(typically means "unreliable: great point to START").

On eBay (refurbished (1 year warranty)

Dress warm... happy hunting
On the HVAC if the controls seem to be working... another

Look through the eBay parts for ideas...

your vehicle... Buy a few spares BEFORE they become rare.

Hope this helps.

How do I check vacuum system for 92 Cadillac devill climate control system?


This problem is most often caused by the air mixing valve (usually its actuator has stopped working - fails in the cold position) so I would start there. Not sure about a 92 - could either be an electrically or vacuum controlled actuator. You can check vacuum at the HVAC control unit with a vacuum tester.

I have a 92 cadillac deville and the fuel data and climate control screens both show a 'c' on them and the heat is on full blast?


the heater is in limp mode if you have electricity experience go to the library and get a manual because that heater does a wack of **** and you need to know how to press the right two buttons at once to get into the heater menus in the actual heater control

Instrument cluster went blank


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.......
