I have a self contained Dometic 5000btu a/c on my boat. It only has a one speed fan. Fan works great but blows to much air(small cabin) and is very loud from air flow. Is there anything I can to to make it a 2 or 3 speed fan?

Thanks for any suggestions

if its a 120 volt a/c you can add a varible speed switch by remobing the old switch and add the new one in line..http://www.ebay.com/itm/AC-or-DC-ELE...-/290491577490

Thanks for the idea. I just looked at the fan and it is 120v and it has brushes.
