Q: The heater will not blow any air no matter hot or cold? on 1998 Cadillac DeVille

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
No blower motor blowing air through vents or heater or a/c.
Bought the module for 1998 Caddy, and it didn't work either. checked all fuses they were good. This is my only issue with my Caddy.

It's under the right hand dash, the blower motor and the resistor. The wires to the blower motor come from the resistor, or in some instances it's called the blower module, and on the bottom of the black housing next to each other.
its your blower motor resistor that is loated on your evap core.
first thing first check your fuse and relays for ac system
let me know
Where is the evap core located? and actually what is it? I have a Chilton book, but couldn't find anything helpful yet . We did buy the electronic module for the heater, . I found one online thru eBay. The exact Unit #. so it does match, but it doesn't work either. There's something else that we re missing with this. i really appreciate your help here with this. Have been working and it for almost 6 months now. and still in a puzzle is there any schematics for this eval core? i will check around on the web, too.
