Diagnostics Codes Cadillac Sedan Deville


97 Cadillac Sedan Deville - Heater/AC Fan Died Lost the blower fans, not getting any heat or A/C. After a particularly slushy day heard a funny noise coming from the heater then it died totally the next day after a cold night. The lights which indicate the blower setting still work. I pulled of the these diagnostics codes and don't know what they represent.

MSM B0856



MSM B1983



MSM U1300



MSM U1136



MMM 2148



Thank you for any ideas.
