Seems my blower motor took a crap.

Pulled all the covers off and the capacitor doesn't look bulged.

What are my next steps?

No model number available as its old enough to have had all the labels fall off.

Cap can still be bad and not bulge. Use a VOM to check to see if cap is open or shorted.

As long as you can check microfarads, yes.

ETA; it may have a setting for mfd, or one of the following symbols.

The price varies..
I never go cheaper than field piece, but prefer fluke.
Check out amazon.

Read continuity across the cap. But first, disconnect the cap, short it out with a screw driver, then read continuity. The put leads (meter set on ohms) on the cap, reading should go full scale and then drop off to about half scale.

Pretty sure it's my cap.

Didn't discharge with a screwdriver and maxing out on my ohm meter with no drop..

Well, replaced my cap and still no go.

I don't think I'm getting power to the motor.

Almost all contractors (the relay that controls power) are single pole these days, so if the compressor is running, there should be power to the terminal that goes to the fan.

Pull on all of the wires (with the power off) and see if any come loose. It is not unheard of for a crimp connector to be bad..either the wire burned loose under the plastic insulation or the metal overheated until it looses its tension that holds it to the mating terminal.

If that does not work, order a new fan motor off of Amazon. You can look up the motor part number by searching for the brand and model number of the condenser (outside unit).

...and be thankful its not August.

Turned out to be a bad relay switch on the board.
