Drivers side wiper doesn’t work. Passenger side works fine

@infamlaw , Cindy, the wiper arm retaining nut may of come loose or stripped. Use the link #1 below to see how to tighten the wiper arm nut, if nut appears to be tight, most likely the arms connection/boss is stripped and the arm will need replaced, Link#2 shows how. Link #3 shows one of many places available to get a new wiper arm. Good luck.
