Fig. 4 Testing fan motor relay.:

Check for continuity between fan motor relay terminals. With no battery voltage applied to relay, continuity should be present between terminals 3 and 4, Fig. 4. With battery voltage applied to terminals 3 (positive) and 4 (negative), continuity should be present between terminals 1 and 2, Fig. 4.
