Driver Side Sliding Door will not open more the an inch. What can I do?

Thank you for your advice. I wanted to update you. I was stumped and after reading a bit online I came across something that I was never told. The gas intake is on the drivers side. In my model you have to pull a lever in the front to open the gas cover, when you do that a hidden lever is activated under the sliding door. That lever is a safety switch to NOT allow you to open the door if you are pumping gas. That lever was stuck up and would not go down. After using something to push down the switch while I pulled the door closed- it opened. Once the door was open I could explore the switch which is visible. I have gotten it to work again. Thank you.

That's great
