No Heat/Blower not engaging
 

I have a 1989 Cadillac Brougham.Cannot get the Blower Motor to operate on any selected speed...Low, Auto, High,or Defrost. I replaced the Blower Control Module (resistor) with a used one. Still cannot get the Blower Motor to operate. I have used a jumper to be sure the Blower Motor operates,and it works fine. Could it still be in the Blower Motor Module??

I cannot get even a tricle of heat into the vehicle. Just replaced all coolant (tested for about 25 below zero. Replaced thermostat at the same time......can't figure it out for the life of me.....The weather is beginning to get cold so I need some heat!!:confused:

Anyone have any idea's? Suggestions? I greatly appreciate any input.

Thank you all for any assistance provided.
