Heater blower switch
I only get blower in the full on all the way up position. In the other spots nothing happens. I don't even know how many settings there are. Is this a contact fix or replace the switch fix?????????????

Inside the heater box is a small plate with resistor wires on it. This is the part that gives you the variable speeds for the fan. It plugs in from the outside(if I recall), so make sure it didn't fall apart. Beyond that it might be broken completely.

One for the standard fresh air heater: C7TZ-18578-F
One for the deluxe fresh air heater: C8TZ-18578-A
Not sure which one you have?
Green Sales (800-543-4959) has both...if you end up needing a new one, they can compare what you have with theirs. That way, you'll get the correct one.
