Question about 1998 Cadillac DeVille
Are you sure that you don't mean the cooling fan control module? It should be located up front next to the cooling fan. It is square shaped and has a long square shaped plug going into it.

The ECC receives analog information and signals the cooling fan switch to cycle the cooling fan on or off, as required.
