2000 Buick Cent. Door problem

It's possible that the outside door handle has broken, or more likely that the linkage has come loose from the door handle. There is a plastic retainer that may have failed at the handle.
Have you ever been into a door before?

It's a matter of removing the interior trim panel.

Recommend getting a haynes or chilton's manual for your 2000 buick century.

It will explain how to get to the door latch.

It's around $15.00 and worth every penny if you're going to be doing work on the car yourself.

Excellent advice! :)

The plastic retainer was the issue. It was no trouble to remove a screw and a couple of bolts from the inside of the door. The door panel eased off and the plastic sheet was easily removed and replaced. I was amazed how easy it was. Took all of 15 minutes.

Thanks all.

Great work! This stuff really Can be fun eh? :D
