Hi, the information center has quit working in my 1992 De Ville. I hope someone can help. The floowing insterments are effected.
Fuel Data Center, Fuel in tank. In addition the Electric Climent Control is not working that controls outside temp display, warmer/colder, defrosters, and air conditioner.

Note all of this stopped at the same time and one would think it's a fuse. So I checked all th fuses under the dash and all of the maxi fuses and they all "look good"

is there any other fuse I should check or could someone direct me to where I should look next?

Thanks for your help,
Ken

 

Is anything displayed on FDC or ECC panels?

 

When I first start the engine, all the sections in both the FDC & ECC panels light up for just a second and then go out. But after this nothing.... and nothing works, no heat, no air, no display..

Thanks for your reply.

Check fuses. If they are both totally blank check for 12v to them with key in run. Orange or pink/black wire - you need a manual(FSM is best) or Alldata for specific info.

 

Thanks Slowroll, I pulled every fuse out and checked them with a meter. I checked every ground wire I could find. One thing is I don't know where the ground wire is for the dash area. Hmmm, I just may have to take it in. I'll let you know what they find. Hey thanks for your help and have a Merry Christmas!
Thanks Again,
Ken
