In my experience...
this sounds like an issue with the cord rewind. Specifically, the spool has likely come away from the contacts located on the stationary part of the assembly.
Check the continuity with a wire tester first to confirm. Start by going from the plug to spade connectors in the spool, then followed by spade connectors in the spool to spade connectors on the stationary assembly. If you don't get continuity on the latter, the issue is what I've mentioned and that can be fixed easily.
Let us know what you find...
