When you say "passenger doors" do you mean the front seat passenger door or the rear seat passenger door?

Have you tried unlocking the doors manually?

Most likely, a rod clip has fallen off inside the door. If this happened to multiple doors at the same time, the most likely cause was someone was attempting to use a slim jim and knocked the rod clips off.

Assuming that the temperature is not below freezing where you are and the doors are not just be frozen shut, then yo uhave to remove the interior door panel to access the hardware that releases the door and to the lock rod clips. It is a lot harder to remove the interior door panel when the door does not open. The doors panel is held on with a combination of screws and clips. First remove all screws (usually screws holding the arm rest and door release lever) and then pull the retaining clips our from the perimeter of the door panel.

Ray, can he use a Slim Jim to open the door with the clips disconnected?...be lots easier to get the panel off...

Just tried it on my 89 and it worked. Slant the slim jim at about a

In theory, yes - if the OP can get the slim jim on the door lock itself.
