The thing that happened was that I had just left work with an armful of stuff. I opened the drivers side rear door and heard something like glass breaking and stuff falling from somewhere towards the bottom of the door. I looked on the ground to see if anything had fallen, shrugged my shoulders and closed the door. The door would not close and I concluded that something had broken in the lock assembly and had fallen to the bottom of the door. The window works fine. The quote from the dealer was $140 parts, $160 labor and shop costs. If this is a tricky fix, I wonder if I should eat the $160 and let the dealer(Toyota, not Lexus - same part from Camry, I know the asst. service manager that I deal with and he is no BS and fair) worry about it. If something doesn't work, I can take it back and have them fix it right. I personally am not crazy about having to take off the panel.
