Question about 2004 Chevrolet TrailBlazer
If you vehicle has the automatic temperature control system, where you can set the desired temperature using the digital temperature readout, then you most likely have a failing blower motor speed control module. This is an electronic module the controls the blower on/off and speed operations and when it fails it often won't shut off the blower when you shut off the vehicle which can result in a dead battery if you don't pull the power supply fuse. Its a small rectangular box located under the right side of the dash [passenger side] by the blower motor and isn't to hard to change. Hope this helps and good luck!
