I have 1980 Malibu and my drivers side door is shut closed. I opened it from the inside and it was hard to open and when I closed it I couldn’t get it back open yet. Any advice would be much appreciated!

Depending on what'* wrong, you'll probably have to take the interior door panel off to get at the mechanisms. To do that, you'll probably have to remove the driver'* seat. To do that, you'll probably have to remove the front passenger'* seat.

What'* holding it up? It sounds like you have an alignment problem more than a mechanism problem.

Good point, maybe lifting it while opening it would work?
