My hubby and I have a 1999 40 SeaRay Sundancer with Caterpillar diesel engines. We are having problems with the salon air conditioner and getting it to go on by itself when it needs to adjust temperature. We are fairly certain it is a relay problem, but we cannot locate the relay that operates this system and the shared pump. We believe it is in the engine compartment, but because this boat has some options other 40 footers didn't we know the boat set up has been slightly modified and some equipment moved around. This particular boat came with a bow thruster, and it was not an aftermarket piece of equiment, so that has caused several things to be modified. If anyone has any idea where that relay may be located, we would greatly appreciate any tips or thoughts you have about finding and repairing it. Thanks!

On my boat the electrical box is accessed by unscrewing and removing the aft vertical salon cushion.
These relay switch modules provide a Boolean OR logic function, turning on the AC raw water pump when either of the AC units is active.
When mine failed the relay went bad. It is possible to either replace the entire module, or get an identical relay, from a company like Digi-Key, and un-soldering the bad relay and re-soldering the new relay.

The bottom of the vertical cushion is unscrewed, the cushion raised to disengage the downward-facing pegs at the top of the cushion, retaining the top to the cabinet shelf.

You probably only need the trigger for the salon unit, but I haven't master posting photos yet, so this is a link to the control box you are looking for:

This is what t he trigger looks like:

I don't know anything about the vendor for either item.....I just wanted you to see an image of what you are looking for.
