However, wouldn't that be the valve to the house? I was under the
impression that each zone had a valve? Will they all be located in one
place or will they be near the zone?

It's fairly common for all the valves to be together
in a box set in the ground with the lid flush with the
surface, simplifies the wiring and protects the
valves from damage. Wouldn't think it would be
very common for them to be completely buried.

Or, some people install their valves above ground.

In any case, start with the controller.

First you should check to make sure that all circuits are
programmed to run. Maybe the previous owner shut off
a circuit or 2 because of leaks he didn't want to fix?

If all circuits are programmed to run, follow the wires
leaving the controller, they eventually have to end up
at the valves.

Once you find the valves, try that wire-swapping thing.
Or, spend $10 on a cheap voltmeter, and check each
valve to see if it's getting voltage when it's supposed
to be opening.

If a valve is getting voltage and not opening, replace
the valve. If a valve is not getting voltage, trace the
wire back and find out why.

Hope this helps,
