What could be causing this The first thing You should try is checking the blades on Your wipers to make sure nothing has become stuck, or that the blades haven't become so overly worn that they are no longer able to rake across the glass. The other potential causes are loose wire connections, and possibly a dead wiper motor. If You need to replace the wiring, it will cost You between $20 and $44. If You need to replace the wiper motor, You are looking at a cost between $50 and $120 for parts alone.

When windshield wipers stop working in a 2012 gmc terrain, it's usually because the ball joints have worn or corroded. There was actually a recall on this part for this vehicle. Otherwise, it could be a problem with the wiper motor.
