I assume you checked the fuses, underhood and under dash the underhood fuse block will have the fuse in it for the blower but underdash has the fuse for a/c heater either one will cause your problem
Cool next remove relay turn ignition on use test lite two terminals should get hot, if so plug the relay in and out, can you hear/feel it click? If yes unplug blower plug does a test lite illuminate? If yes check blower ground.
