The blower motor on my 90 Accord just went at the perfect time --
snowstorm, not predicted to get above freezing until at least mid-month.
I got in yesterday and noticed that 'whiff of ozone' smell
characteristic of a failing motor, and sure enough, the air stopped
coming shortly thereafter. At least when the car is moving fast enough
the flow-through gets some warm air out the vents.

I've just started looking at replacement parts, and it seems like I can
get either just the motor or a whole new blower assembly. Which makes
more sense? What are the issues involved?
