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.

"obd II diagnostic fualt codes" by Peter David. Got it at amazon for $25 bucks. Not a bad book to have and to keep with your scan tool.
