Ok now this car, guess it's now my car. Anyway the heater motor for does not seem to be working. But I have experienced the heater working a few times. But not with any force of air behind the heat. Now when I look up for replacement heater blower fan. It shows the squirrel cage part. (Or what I call squirrel cage is the round can wheel.) But then there is also a pic of An incase fan heater / blower fan.Sooo how do I know which part do I order. Being the blonde that I car with cars.
