Have RV Questions? Ask an RV Mechanic Online.
This can be caused by several things...........and most often it is either the springs are rusty and won't move OR a cable has come off and jammed in the space next to the pulley. I am enclosing a link to the most popular popup blog which has manuals and "how to" stuff for situations like this. IF you can find a local mobile tech to come and assist you that would be best. He (or she) would be able to assist you in sorting this out. Please get back to me if you need more as all follow ups are included in our fee. R.J.
