Smoked a new blower motor?
original blower motor went out a few weeks ago, I replaced it with a cheapie made by Seimens. It had blown a couple of fuses the last several days. Today I started up, and it made a strange groan, while heavy thick smoke poured outta the vents! I panicked, shut off and quickly disconnected the battery with pliers.
After making sure that nothing was on fire and letting things cool a bit, I unplugged all the HVAC connectors, reconnected the battery and came home.
New Blower motor is SMOKED totally. I already picked up a warranty replacement, same brand. Resistor is fine, fuse did NOT trip this time. Before I plug in this new one, is there anything else I need to check that could be taking out the blower motor in this fashion?

Update, I went ahead and checked alt output, 14.47 volts, thinking that overvoltage caused it.
Taking a deep breath, I plugged everything in and reinstalled the fuse, its working again, gonna stink like burnt wire for awhile, and I might park it away from the house and anything else valuable tonite LOL.

I'd say that you just got "lucky" and had a bad blower. I can't think of any fault in the car that would produce enough voltage to smoke a good motor. The motor probably had some shorted windings, or bad bearings.
