Heater Fan
Well its starting to get cold here in Iowa so I started up my bronco and turns the heat on but nothing happend. The heater fan doesnt' atcually kick on untill I have it on the highest setting. Does this mean my blower switch is bad or the blower itself?

Yep, I think Nobody's got it pegged.
Just did the same thing to mine. On the highest setting the fan works because there is no resistance "in-line" with the blower motor. The other positions use a wirewound resistor to slow the motor (higher resistance = slower fan speed). Anyway, pull the plug, pull the resistor pack (2 screws) from the engine side and get another one. They don't go out often, so a pull from your local junk yard will most likely yield you a good one.
