Re: Zip Dee big awning won't rewind.

If, just if the spring tightening maneuver produces a "click, click, click instead of progressive tightening of the spring then the cam on the retainer is slipping. There is a small indent in the roller tube about a third of the way out from the winding end. There is a cam on the end of the spring that is supposed to "catch"on this indent. Sometimes it doesn't. A pop rivet into the tube may be necessary.
I would call Zip Dee and they will talk you thru this repair.
