1994 Cadillac Deville Heater/AC blower moter keeps running

[New Cadillac Man]

Hello and hi to all of you,

I am new to the world of the Cadillac. I bought a nice 1994 Deville for $500 at auction. I replaced the water pump and put two new tires on the front. It is my daily driver I use for work, I put about 96 miles a day on it. The gas mileage is actually really good due to 90% of my drive is on the highway.
The only issue I am currently having is that the Heater/AC blower motor keeps running until I pull the plug under the hood. I started looking up solutions only to find that there really seems to be very little in the way of getting good information.

I have one side saying it's the blower motor itself
another saying it's the BMC
another saying it's the heater/ac programer
and still another saying there is no cure just pull the fuse


When I checked here I found one person with the same problem back in 2011, but there was no resolution.

Is there anyone here who has had or knows of this problem and the correct way to repair it?

Thank you for your time.

It is definitely the blower motor module found in the HVAC box under the relay center

WOW!
That was quick, thank you.

I will check that this weekend after I put new brake shoes on the car.
