The one I replaced on my son's last truck would have been a great candidate for that. Completely melted potting, circuit board was dangling within. I'd never seen one that bare that hadn't been completely engulfed in flames at some point. But it actually ran good like that til it didn't... It was like someone flipped a switch.
To be honest though I have never owned any other brand of vehicles besides Mopar, I think that's one of about 1 that Ive ever had go bad on me... I've replaced them on fords and GMs over the years though
