Winterizing AC Question - 2014 R31

[Happy Place]

How do I get the AC pump running when it's cold in the cabin?

I went to pink the sea strainer for my AC but when I turned on the AC breaker on the panel, nothing happened...the pump motor didn't come on. Then I realized that the cabin temp was around 50 degrees and the thermostat only goes down to 65.

What am I missing?

Have you tried switching it to the heat cycle?

Or put a “tee” in the line somewhere between thru hull & a/c pump…..a flush line! Can be used to flush system with fresh water or introduce antifreeze….will have to close thru hull to make pressure flow to pump.
I have even run my ac with fresh water ( dock hose bib) as the cooling source while flushing after saltwater use.
