I'm stumped. While parked in my garage with everything turned off...the blower motor sometimes just starts to run and continues until the battery is dead. Temporarily, I have installed a battery terminal disconnect to protect against this. I sure need some suggestions on a trouble shooting, fault isolation approach to resolve the electrical fault and rid my ride of electron ghosts.
Thanks

That's strange. Wonder if the blower motor relay is gone bad, but with the key off there shouldn't be any power going to that relay.

Using logic, I think you might have a problem int he ignition switch, it's not cutting power off to the car.  

Thanks! I'll start the troubleshooting at the ignition switch and see where that leads.
