My raw water pump for the A/C system is not turning on, pump is good. Does anyone know where the relay is for it? Lunaire 16k system. Thanks.

Factory system? Not working on both ACs ?

[jfgkahaluu@gmail.com]

Yes Factory. Raw water is not turning on for either system.

I have run a hose through and the front A/C is blowing cold, main salon A/C needs a charge but compressor kicks on and everything seems to be working just not cold.

Did you check for power at the pump. should be a relay box near the units

[jfgkahaluu@gmail.com]

Yes, no power at the pump when the A/C is running.

The relay box that controls pumps may be under the dinette.
