Cords for an Eureka Oxygen 6992A

\015 The plug connection between lower wand and the motorized nozzle seems to be partially burned out and does not maintain contact. Therefore, the nozzle works for a few seconds and stops. Can I purchase the cords I need? Is it possible to replace the cord on the motorized nozzle? I don’t see the cords on the list of parts available to purchase. Our local vacuum shop would not fix it. Thank you.\015 – Eureka Oxygen s 6992 Bagged Canister Vacuum
