Mine just failed on a 11/04 with almost 64k miles. I had 2-3 failures a few months ago but with stop and start again the car the problem fixed for that time. Yesterday the pump didn't stop to run even with the ignittion off so I disconnected the battery. So, at the momment I know that the pump is still working but not properly. I have read from this thread that a good cleaning might help and I am going to give it a try. But I would like if anybody knows to tell me what kind of brushes am I going to need in order to change them also. If you have a part number also would be great.
