First thing to do is check fuse with a test light/volt meter if that is good then pull the relay in picture and check for corrosion on prong. Try to clean it off if any, and tweak it a tad then use dielectric grease, about $2.00 at auto part called bulb grease. If not that check fuse box and check green wire with test light when hot to see if PCM is telling relay to turn on. Also, check where relay plugs in to see if power comes in. One other thing when A/C is turned on other fan should work so do same on those wires in picture. This may be a fuse box problem. If everything else is working okay.
