I don't know what the deal is, but the heat has now failed in both our car and our apartment. Or rather, it's mostly failed. It works about a quarter of the time in the car, not nearly reliably enough, so when it does kick on we're only too happy to strip out of our layers of fleece. And then it shuts off again just as we're getting warm, and we get to dress while dodging LA traffic. In the apartment, the heat works well enough during the day that we leave it on when we go to bed. Then it shuts off sometime during the night. Not enjoying waking up and seeing my breath. And not fancying a visit to Washington with its current blanket of frosty on the ground.
