Spare Switch on 12V Panel Turns on Fan

[gmac98004]

Hello Everyone,

We are just starting to get involved with our new (to us) 1998 355 Aft Cabin. It's in top shape and we love all of it!

One item came up the other day. We turned on a "spare" switch on the 12V panel and a fan was started.

The Red Dot was NOT on and the fan exhaust seemed to be coming out of the heater vents throughout the boat. It was cold air.

Any ideas what I've stumbled onto?

More crazy and ridiculous questions to come. Thanks for everyone's help.

Take Care, Greg

If your boat does not have big sliding salon windows then I bet you've stumbled on the fan to bring in fresh outside air instead of opeing a window. Seems 1998 is when they changed window designs and so no sliding windows. Personally I like opening my windows on my boat others may not care as much.

On my 356, I have a fan switch that is mounted on the wall just aft of the electric panel. Air came out of the vent mounted on the side of the galley peninsular. If it comes out of other vents in the boat, I didn't check.

I agree with you whenever I can I open up all my windows and hatches to let in fresh air. My boat is an 81 and it does after being closed up for awhile have that "old boat" essence.

We have two rows of windows, we have them open as much as possible.
