hey John - what is the outside temps when you kicked the a/c on high? Did the fan start immediately when you put the a/c on both arrows? Come to think of it - what does the unfilled arrow on top with filled arrow on bottom actually mean? what does both filled arrow switch mean? (sorry - no owner's manual)
When the outside temp here was 77F and I put the temp dial to minimum and the two filled arrow switch on - a/c cooled like a banchee and engine temp stayed below 95C for over a hour and the aux fan never kicked in.
