The A/C control system has been acting oddly lately, but tonight the fan stopped running. Everything appears normal otherwise. I checked the obvious fuses and they were fine. I just looked at an earlier thread on an 86 DeVille with a similar problem and relays, motor resistor and computer were all mentioned. I'm suspecting computer. If it's that, where would that be located on a 2005, and how much to fix? Help much appreciated! Frank
