I scoured LOST for a good how-to on replacing the KK's blower motor and blower motor resistor, and came up empty. There is a very well illustrated how-to on Jeepforum, though. Rather than reinvent the wheel, here is the thread by lsejlowe on JF:

How to know which is causing your problem:
It's the blower motor if the fan isn't spinning at all or makes a grinding/screeching sound.
It's the blower motor resistor if not all your fan speeds work (typically only blows on high).

I replaced the blower motor in my '08 this year. The bearings went bad, so it sounded like a helicopter taking off.
