If it does have a fuse and that fuse is blown, then it is blown for a very good reason. It is not wise to simply replace any fuse until the fault has been identified and corrected or you may cause irreversible damage.
At the very least, thoroughly dry the charger out as I previously described before reapplying power.
Also I disagree with the suggestion of simply blowing air through the charger to dry it out. Moisture invariably gets into electrical components by capilliary effect and is not simply removed by air passing over the component. Gentle heat on the other hand vaporises the moisture and it is expelled. Placing the whole thing into a vacuum chamber is by far the best method but not everybody has a vacuum chamber readily available.
After it has been thoroughly dried you could consider replacing any fuses and restoring power.
This information has been gained from much experience with water damaged electrical and electronic equipment.
