The issue with your RV window blind appears to be a broken spool causing the string to come loose and the shade to only open on one side. The blind itself is still in good condition and can be repaired by restringing the shade. We recommend following the detailed restringing instructions available at https://www.irvineshadeanddoor.com/wp-content/uploads/2019/06/Re-Stringing-Diagram-1.pdf. If you prefer not to repair it yourself or via an installer, and the blind is deemed unusable, please contact us to arrange a replacement. Note that since these are custom items, replacements will require rebuilding. We're here to assist you through this process to ensure your RV blinds function properly.
