I own a 2000 Buick Century with a two dial system for the vent/Aircon. The blower motor fan won’t shut off when turned to “off” position. Problem first arose when I had the A/C on and the mode dial on VENT. – it’s HOT in Florida – the system simply started blowing faster as if I had turned the mode dial to MAX. What could be the problem….its draining the battery when the car is turned off.

The problem you are having sounds like a common problem of a burned out blower motor resistor or control module. These are two names for the same part, depending on your system. When they fail, they short out internally and cause the blower fan to stay on all the time, only work on a few different speeds, or stop working all together.
