IF you are mechanically inclined, take off the cover, and see if you can get the cord to rewind. The idea is to determine if the rewind spring is broken, or cord merely jammed. If necessary you can GENTLY pull one of the tabs up holding the pulley in place. Do not break off, and do NOT use extra tabs unless you do break one. If spring is broken, or pulley is worn, you need to buy a replacement spring & pulley and replace. CAUTION if 3 tabs break off, you are off to a repair shop.
