BTW, notice this statement is relevant to dead batteries:
"You don't need to have the key on to check the blower motor, 12 volts is always at the FSU connector."
Wow! This is just what I was looking for. I replaced my FSU about two and a half years ago and it just went out so I just replaced it again. It worked for a few days in the same manner as the old one and now has completely died out. This will help determine if it is the blower motor or just a bad brand new FSU. Thanks. Will update.
