Will a rear side door from a 2002 Chrysler PT Cruiser fit a 2001 Chrysler PT Cruiser?

Yes, a rear side door from a 2002 Chrysler PT Cruiser will fit a 2001 Chrysler PT Cruiser. Both models share the same platform and body structure, which means their doors are interchangeable. However, it's always a good idea to check for any specific trim differences or color matching if aesthetics are a concern.
