2 lawn sprinkler heads next to fire ant mounds, tho open, don’t work even after killing the ants. How fix?

The sprinkler heads are clean & aren’t filled with dirt . I can blow through them but water doesn’t come through. Do Fire ants get down deep into & stop up the pipes? I am partially handicapped and can’t do much digging. Is there another way to solve the problem and get the sprinklers working again?
