Windshield wipers

Wipers would not turn of at first. After they did, we only heard a motor like sound, but no movement. Now there is nothing! My daughter cannot afford a new car, and as her mom i have fixed or repaired things with the help of videos or manuals. yes even replaced a starter! Lol. But only after some great mechanic has told me what to check for :) At fifty four and on disability i cannot afford to help her purchase a new car. So if you can tell me what i can look for id be so grateful! Thank You. Sharon.
