4. And, not exactly related to the heater - How do I remove spade terminals
inside electrical plugs, specifically the cylindrical connectors for the
climate/ac switches?  I need to replace one of the female terminals, but
can't seem to remove it from the plug.

Thanks,

        These contacts usually have a very small barb that sticks out
of the side and prevents it from falling out, of the connector
housing.  Most require special tools to remove properly.  I have
found that with a very small ice pick and a good flashlight, you
can jag the barb to the piont that it with let go.
