The Fan Module under the hood makes way more sense (pulse-modulated output) but I know is way more complicated.
I keep my top down a lot, so I guess mine will last and last since the fan in the HVAC is used less than most.....
I guess they use resistors, simple, cheap, and as it turns out not too reliable.
It is a potentiometer with fixed increments, I guess. The fins dissipate any heat and heat is probably the cause of the failures. These are all guesses on my part, how it works I have no real knowledge, but I would like to know. Lots of guesses but MMZ will let us know.
