You can pull the fuse to keep the blower from running down the battery while you work on the problem, which is either a bad ignition switch or a short circuit somewhere in the blower motor, switches, or associated wiring. Your mention of another problem with the fan switch is not clear, but that would be a logical place to start.

There is a “fan speed controller” in the plenum that would most likely be the problem.

Maybe this car is working as designed, what I mean is I installed alot of GM “afterblow” kits that kept the blower going and the bacterial growth on the evaporator down. They time-out after 30 min though.

Ignore that last post. Apparently the 2006 Malibu does not have the “speed controller”
