Are the fans working at low speed with a/c on, engine cold?

Check for the 12 volts on two out of 4 terminals at the base of the ENGINE MAIN relay in the fuse box with ignition on , engine not running and relay out. This relay despite word "engine" in its name is swithcing the power to the fan circuits with ignition on

The engine main relay fuse is missing! Is there a reason some one would of taken it out! Maybe thats the whole problem

Is it 7.5 A fuse? If so Is your "charge" light ON with IGN .ON, engine not running
