What is the specific symptom? Why can't you ask this question? Do the wipers work normally , but do not 'park' in the proper position? Do they not move at all , but you can hear the wiper motor running? Do they hit each other while operating? Did they get turned on when stuck in ICE? IF the problem is a defect , then yes, it should be warranty , but if other factors such as ICE caused the problem , it may not be covered.
