Turn Signal problems of the 2001 Dodge Caravan

Our Dodge Caravan sport has been well maintained and we've had it for 3 years and has only 35,000 miles on it. This started happening after the 30,000 mile mark. We have 2 small children and we have been very lucky that nothing has happened. We liked the Caravan because we did not hear bad things about it. But now we experienced these things and we are not alone makes me re-think of not getting a Caravan again or recommending it to people. We've run into the following problems: first item is the power door lock on the sliding door. While on the freeway, the lock would unlock and lock. Second item is the power windows on the front passenger side. I've read others who complained about it. The power window does not go up after it has gone down. An effort to giggle it up is the trick. Now it just doesn't roll up or down. Third item is the power steering. We have a family friend who also had this problem. The power steering is making clicking noise and while parking it has a loud agonizing hum. Fourth item the turn signals does not turn off automatically once the turn has been made. Taking it to the dealership, see if they have some answers.
