A/C worked 1 day, but not the next??? 1998 290 Sundancer

[CoronCoron]

The cabin was a cool 68 2 days ago, the water was a good steady stream out the thru-hull and life was quite good.
Yesterday I turned the A/C on and I could hear it turn on under the first interior step and air was coming out from the vent but NO COLD! No water came out of the thru-hull.
What should I check? I've only turned on the A/C these 2 times since I bought this 8 months ago, so I don't know how to troubleshoot it.
Thank you

Make sure the seacock is still open. Check to see if the strainer is clogged; maybe debris got sucked in last time

What and where is the seacock?
Also, is the strainer underneath the step?
Thank you for your reply and I will be there this weekend

The seacock is in the bilge where your system draws the raw water supply. Opens and shuts by way of a lever. Since you had good water supply the first time, one would assume its open. The strainer (filter) is next in line and is in the bilge also.

Did the thermostat show a code?

Look in the engine compartment.

If you look behind the table that's stored there you will find your AC water pump that is directly plumbed to a strainer and then just a little further to a seacock. It's right next to your generator seacock and strainer.

Close the seacock and then open the top of the strainer. There should be a removable basket in there that can be removed and cleaned. Just watch the wingnuts. If you do have to remove them all the way they are easy to drop and they just disappear somewhere.

Dear god, make sure seacock is closed before pulling hoses. If not sure, find some old grizzled guy at the marina he can explain.
