My heater doen's turn on. Can the heater motor cease? I just moved
to Minnesota (from SoCal) and it's cold here.

I should be able to test the voltage where the heater's electrical is
sourced..... right? If there is juice, can I assume that the motor is
inoperable? (BTW...I haven't yet tested any of this)

Has anyone ever encountered a similar problem? And is this the best
way to approach it?

I'm not interesed in upgrading the unit.... I just want it to work.

Sure the motor can cease. Before you panic too much take a little time and
clean the electical connection on the back of the motor. It is very easy to
get to, and gets fouled up very easy. It is just one wire, that plugs into
a little blade than goes from the engine compartment through the firewall.
And once it is clean you can use your voltmeter to test if you have voltage
at that point. If you don't have voltage it is a electrical problem before
you even get to the motor, and if you have voltage you need to look at the
motor more.

And if it is the motor, you need to tear out the entire heater
box assembly INSIDE the vehicle to get at it.

As one who lives in Minnesota already, I'd suggest taking the
heater core to the radiator shop and have them clean it out. You
will also want to check (replace) your thermostat, and install
the heater fan update:
