Do the whole interior car handle needs to be change?

I have a 2010 Ford fusion; the passenger door handle feels like it jam. It causing the door not to open from the inside but can on the outside.

There's a good chance that something is broken.

You'll have to remove the inside panel; start with the armrest.

The inside handle is at the front of the door. It operates the latch, at the rear of the door, by pushing or pulling on rods that run front-to-rear. Chances are that something is bent, or a connection has come loose.

This can get complicated, but isn't dangerous or difficult.

Need to open the door panel to see what the trouble is. It could be as simple as putting a clip back in place on the operating rod or as complicated as replacing the inner handle. Arguing with the car will not fix it.

Without opening the door panel, there's no way of knowing what is wrong.

Look on youtube - even if there aren't instructions for doing the handle, there will probably be more than one showing how to get into the door panel to change speakers.

Once you are in - you should be able to tell what is wrong.

Ford uses plastic parts in the door handle linkage. The inside and outside linkage is independent of one another. Perhaps the plastic part for the interior handle has broken inside the door.
