We just purchased a 2000 Quest van with 123,000 miles. The drivers side window would not go up once it was put down until you turn off the car and then restart it. Then the window would function once again. Well, so much for that quirky operation. Today I put the window down and it will no longer go back up. I've read many forums and the most likely remedy was to clean the switch and the contact points, but there is no really good explanation of how to get at the parts to be cleaned. I would appreciate a really detailed explanation of what I need to do to remove the switch or at least get at it, remove, or pry it apart so that I can clean it. I'm not sure how to get to the switches and remove them. I've heard that this can be done without removal of the door panel. All of the other windows work fine from this master switch. Your help would greatly be appreciated!
