I've used this plug-in thing for several winters, but suddenly it broke – I believe the Achilles heel of this item is the wiring near the plug, which seems to have frayed.
If anybody has a functioning plug-in heated seat to give away, I'd be grateful.
Alternatively, if anybody knows how to repair this item, that would also be appreciated!
And failing that, I guess I could just donate this item to anybody who wants a non-heating seat cover....
