To get the door to open you will need to remove the inner door trim panel to get access to the locking mechanism. With the door trim panel removed you can study how the lock and linkages work. Its hard to remove the door trim panel with the seat in the way so fist try "flooding" the door lock mechanism with WD40 by gently prying back the window seal and using the straw nozzle of the WD40 can point it toward the lock and see if you can get oil into the locking mechanism. I just had a similar problem with a Range Rover, I moved the window all the way down, sprayed in penetrating oil and with a long flexible light ( http://www.parts-express.com/1/1/10046-lisle-32250-flexible-flashlight.html I am sure you can get a similar tool at Sears or a local auto parts store.) I was able to see how the lock and linkages worked and open it using a coat hanger, but it was complicated. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.

I have the exact same problem on my 1999 Olds Aurora! How did you fix it? Can you remove the door panel without opening the door? Thanks for any help. Henry hrvalentine@comcast.net 978-582-9056
