Brake light short?

My 92 wagon displays a brake light warning on the cluster. It doesn't do it every time. Any recommendations on how to isolate the problem?

First thing is the check that all your brake lights work. There are sensor boxes in the outer two tail lights that are supposed to detect when a bulb burns out and turn the light on the dash on. I have problems with some of mine when it is wet outside. If all the lights work, then the issue is probably in one of the boxes.

You should have posted this on Saturday, I was in your neck of the woods (Roberts Road near where it crosses over I-70).

Dang! I have checked all the lights on multiple occasions, but they are all lit up. I spoke with autozone & napa and they both seemed to think it could be a brake switch.

Usually when its the brake switch the lights would stay on from my experience. Honestly I would try to get one of the sensors that go into the taillights and then eventually it will turn off once you change one or both of them.

Are the sensors built into the lights?

Yes, they are mounted inside the tail light assembly; items 34 and 35:

That's going to be fun to fix!

Double check that the bulb contacts are in good condition

It doesn't necessarily require you to remove the tail light assembly; I'm pretty sure the sensor can be replaced with the lights in the car. It is more difficult to get to them than a sedan or coupe.
