Hello and welcome to just answer,
There is a lever on the handle that pulls the latch rod that typically cracks and lengthens
the distance need to pull the latch, to repair this the inside door handle is replaced, sometime the latch rods stretch at the bends also and you can shorten them a bit by bending them a little.
I am sending instructions for door panel and door handle replacement.
You will need a door panel tool to pry the door panel retainers from the door you will also need a drill and bit to drill out door handle rivet, you will need a rivet gun to reinstall the rivet, (you can use a screw in place of the rivet but not recommended)
Also you will want to get a few extra door panel retainers because a couple will usally break in the process of removing take one of your old ones to the part house to match it up, I have done several dozen of these and always manage to break one or two.
Below is an example picture of the door panel tool, a part house will typically have these for around 5-10 dollars each.
First, Door Handle Bezel Replacement (Front Door)
Insert a flat blade tool between the door inside bezel and the handle assembly.

Using the door panel tool , carefully pry the retainer from the retainer seats. Disconnect the courtesy light connector, if necessary. Remove the trim panel from the door. Remove the courtesy lamp lens or the reflector.
Pull the retainers from the slot in the trim panel. Remove the retainers.
