1993 Cadillac Sedan Deville (blower motor relay)

I am trying to figure out where on earth the part is located in order to replace it. It is also called blower motor module from what I understand. Does anyone happen to know where I could find that joker? Thanks so much in advance!

the ECC (electronic climate control module) is on the firewall to the left of the blower motor as you are looking at the blower. The ECC gives the blower different voltages to run the different speeds of the blower.

What is the problem you are having with the hvac system? Your HVAC system is very complicated. It uses a ECC programmer behind the glove box, ECC control panel, BCM behind right side of the dash, the PCM behind the rigfht side of the dash and the ECC power module in the right rear of the engine compartment on the firewall to the right side of the car from the blower motor. So that would be to your left as you look at the blower.
