How would I test the refrigant pressure switch for this car without a handheld tester?

You can test it using a test light. Here is a guide to help show you how:

You can test for a ground or power connection through the sensor. Here is the location (below).

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
