1984 GMC 1500 Sierra, interrior passenger door handle sticking...

[Isotope]

I have an 84 GMC Sierra. The passenger door handle has become difficult to open from the interior. When you pull the lever to open the door to exit, its extremely tight. In fact, you have to press the lever closed, as it does not retract. The exterior button on the door handle is fine.

Any suggestions?

I'd take the cover off by removing the Phillips head screw and take a look back there. Then you might have to remove the door panel.

Thanks! Would you happen to have, or know where I can track down the schematics for the interior of the doors? The doors seem rather straightforward, however I would like to know what I'm getting into.
