Which side or section are the door jams, the inner part with the door latch? Or the part that the hinges are on?

All the above plus more.

It's that entire area where the door seals.

Basically the jambs are everything that is painted body color that you can't see with the doors, trunk and hood are closed. smile.gif What is in the trunk area painted body color is the trunk jambs, what is in the door areas painted body color are the door jambs. Under the hood is a little different, you would call the underside of the hood the "hood jamb" and the inner side of the fenders that are painted body color the "fender jambs. The firewall is simply the firewall.
