Ac/heater question

[Jsucci]

I have an 87 trojan 10 meter international express. Got it in the water this year and turned the ac on, everything worked fine. Fresh water was circulating like it has for the few years that I've owned it. Turned it on last week and the ac blows cold air but no fresh water coming out the side of the boat. Any ideas/suggestions? The ac/heat unit is located in the bedroom right behind the wall by the couch. I tried looking for a fresh water pump and filter but not sure where they are located. Any help would be appreciated. Thank you in advance.

I moved this to the Boating section. And this is an express, not a mid cabin correct?

Yea. Thanks.

the rw water pump is a MARCH and is located in the engine room. forward.

The seacock for the HVAC is also forward in the engine room, to starboard, just forward of the stbd engine seacock.

Simply follow the lines.

Test for 120 volts AC at the pump when the AC is turned on - BEFORE THE UNIT GOES INTO SHUTDOWN MODE

BEST!

Thanks, ill check that when I get off work. I tried following the line but.lost it. Now i got an idea of where I'm looking I should have better luck. Thanks again.

Checked for the pump with no luck. I found 3 hoses and traced them out. The 1st one just drains into the floor to the bilge pump, The 2nd is where the fresh water is discharged towards the front of the boat, the 3rd goes back to where the steps are and goes out of the boat. The red circles on the picture shows those 2. I remeber winterizing it and the water came in towards the front of the boat. Am I missing an access panel somewhere that I'm not seeing?

The fiberglass filler panel above the aft gunnel indicate this is not an express.
It's a mid cabin.

Perhaps Bob Dunne will chime in here.

BEST !
