Thanks for the feedback!
Thank you for the feedback! I do have the CD and looked in vain for maintenance info for the retainers. It does show how to r&r them, but the only maintenance related to this area I could find was to lube the door hinges. I think I will replace several of the retainers, as the driver's door doesn't stay open on it's own either. Maybe our rainy Pacific NW weather got to the retainer?
