GMC Repair: GMC sonoma, gmc sonoma, windshield wiper

Question
My drivers side windshield wiper stopped working last night when I went to use it.

Answer
check to see if you can move the wiper arm by pulling on it, if it moves back and forth then you have stripped the arm at the motor, you can try to remove the arm, clean the grooves out on the wiper motor end, if that does not work you will need a wiper arm.
