How do you take off Vintage 1957 volkswagen beetle interior door handles to remove panel and fix window?

The door handles and window cranks should have a plastic trim ring between the chrome handles and the door panel. Also, behind the door panel is a spring.

Push the door panel and trim rings toward the door. This should reveal neck of the handle. On the neck, parallel with the door, you will see a pin about the thickness of a cocktail straw. Get a hammer and small punch to gently knock out the pin. Then the handle will slide off.

After that you can pull the edges of the door panel away carefully to access the window mechanism. But take note of where the spring is located and its orientation when you remove the door panel so you can reinstall in the same position.

Good luck.
