Hello! I have a 1990 Cadillac Deville, 4.5L V8 PFI, 75,068 Miles. Today I was driving and all of a sudden the SERVICE ENGINE SOON light came on and both the Fuel In Tank and Electronic Climate Control read outs started showing a “d”. (See pictures in links below). https://i.imgur.com/urkMrQF.jpg https://i.imgur.com/jnIw9xU.jpg https://i.imgur.com/VXwOqxk.jpg Gallery On top of this the Air conditioning fan started blowing air from the dash, not hot or cold, just ambient temperature air and I can’t change the Climate Control or see the fuel level anymore.
