Windshield Wiper/washer Switch problems of the 1997 GMC C1500

Power steering assist tends to pull the wheel to the right or left with too much assist after barely turning the wheel one way or the other (has always done this since new). Windshield wipers have recently been acting up when activating the washer mechanism. Sometimes they won't work, sometimes they stop in the middle of the wipe cycle. The date below is a required field, but the incidents have happened numerous times since I purchased the vehicle new.

While driving windshield wipers malfunctioned which may caused visual difficulty, and could have resulted in a crash.
