AUTOMATIC BACK DOOR SYSTEM FAILURE on 2005 Nissan Armada

The back door of my Armada started not going up or down when I hit the button. It seemed as if the air pump was bent(not sure how). Now the door goes up, but comes crashing down. How can I repair? Replace air pump?

I had a similar problem. The screw that mechanism pivots on, where it connects to the body had fallen out. I removed the cover that the lifting passes through on the left side of the door. I could reach in and put a new (metric) screw in and the problem was resolved.
