Windscreen Wiper

I had the car wiper pump motor replaced at the weekend. I took the old one apart to see what was wrong with it. I had to break it apart to see inside. The fluid comes in at one end and there's a rotor which spins one way to make the fluid go to the front wipers. If you reverse the current the rotor spins the other way for the back wipers. It was interesting. I took the bits into work to show people.
