After doing a search for you, here is a link to a YouTube video that shows you how to replace the door handle. In the video you will see how to get the inner panel apart. You will also see the linkage from the door handle to the latch and the cable running to the inside door handle in that video which will give you idea of what you should be looking for as the two door handles work the door latch. These are the parts that you need to move, push, or pull to trip the door latch open. Look inside at the door latch and try pulling or pushing on the linkage to trip the latch open. Good luck>
