The blower for my a/c heat kind of intermittently works. It seems to only work when it wants too. Trying to figure this one out on my own as my funds are extremely limited. Any ideas?

Your profile notes 1stGen SportTrac V6, but not much else; what year 2001~2005?
What are your AC heat problem symptoms exactly?

If blower only works on high, likely bad blower motor resistor.
Here's a video on replacing that resistor:

If air blows out of some vents, not others, likely bad vane actuator behind glove box.
Could be a clogged HeaterCore, bad\leaking HeaterControlValve, bad\stuck ThermoStat,...
Any recent Coolant system maintenance or changes\mods: ThermoStat, Housing, CoolantFlush+Fill,...?
Do HeaterHoses get hot with heat switched on in the Cab?
Does engine come up to normal operating temp, ~halfway on your ClusterGauge.
Any coolant smell or leaks?
