07 commander 4.7 electric fan help

.7 commander 64,500 miles


When I put a/c on the compressor runs but no cold air and no electric fan on radiator.
What I did so far is pull plug at fan and read it with volt meter,
with truck running and a/c on I get 18 volts then it drops 15,12,9,down to zero.

When I plugged it back in the fan came on(though not as fast as I remember last year) then slowed and stopped.
Still no cold air but the compressor is on.
Any way to test the fan with a ohm meter?
And any relays that I could check?
Any clue where the electric fan relay is?

Dont remember the fan coming on at all this winter when the defrost was on although the a/c light would come on.
Last summer Id hear the electric fan come on with the a/c.
