Air conditioner not cooling

[Mark Redmon]

Hello,
My 2005 275 Explorer's A/C is not cooling, and the 110v pump that is connected to the raw cooling water inlet is not pumping.  Where is the a/c unit located?  Is it on the port side behind the mid-berth wall?
Thanks,

Thats where it is.There should be an access panel or hatch

There is a small 6" x 6" air intake, but nothing big enough to access the entire unit.  Does the entire wall have to be removed?  I believe it is screwed in place.
