97 DeVille No Heat
 

The heat is not working and the Blower is not working, but the blend doors move. One lead to the blower is hot all the time even with the ignition off. Does anybody have a diagnostic list of procedures for this problem?
ACM B1315
SDM B1136
TCS C1233
MMM B1249
These are the 4 codes I am getting from the on board computer.
Please help as winter is almost here.
