1993 Toyota Corolla Door handle replacement

You have to remove the door handle screws (usually conceiled behind a trim strip on the handle), the interior door handle, the window arm or power window switch.

The panel pulls off, then pull back the door water guard. The handle is held in place by two bolts. Be very carefull removing them so as not to bend them.

A Haynes manual or the car repair link in this thread will also give you reference material to read.

The bolts that hold the handle to the door skin must be removed with care so as not to bend the door panel.
