I NEED HELP! CHEVY COOLING FAN NOT WORKING

1994 Chevrolet Corsica

Engine Cooling problem
1994 Chevy Corsica 3.1 6 cyl Front Wheel Drive Automatic

Hello my engine cooling fan is not working, will not work even with a/c on, the fan motor is good, I tested it. Bought a new relay, my relay has 4 prongs, the 2 on the right have power, tested with test light, also have a new cooling temperature sensor. When I unplug cooling temperature sensor fan kicks on and plug back in with car running fan stays on, shut car off and restart, fan will not come on. It seems the computer is not grounding the relay to kick the fan on. Do not really know any help would be appreciated, maybe another thing to test. THANKS

Check a/c clutch relay and a/c pressure sensor

Would an a/c relay keep the cooling fan from coming on, even if a/c is not on? Thanks
