I am having a problem with the latch on my barn door style/tailgate. The latch (handle) does nothing when pulled on to open. There is no tention in the handle when pulled ot open. This is the INTERIOR latch to open the second door. I CAN open the outer door, just not the secondary door. I've looked at the plate sitting aroud the latch and I can't see where it would come off @. I'm not sure if the spring in there is broken or what. Has this happend to anyone? Or does anyone have any suggestions?? Thanks- TOD
