What I need you to do is check to see if there is power to the wiper motor when it doesn't work. If there is power, then chances are the motor is going bad.
As far as the check engine light, take the car to a nationally recognized parts store and have them scan the computer for codes. Most will do it for free, and then you'll know what is causing the light to come on.
Let me know what you find.
