I have a 2000 jeep cheroke sport and for some reason all the other doors wont work. Do I need to get whole new door peice or is it an easy fix?

 

Please elaborate on "not working" and "door piece". Are they locked and you can't unlock them and are you refering to the master lock on the drivers door being bad??
We would like to help but your terminology is way too vague for us to help much.

 

a lil bit more info will give us something to run on
