Anyone here been exposed to these on a smaller FWD Euro? Not a full CANBUS module, just tri-modal (off/slow/max) with a heatsinked transistor pack not unlike many cabin blowers.
Got what appears to be a faulty one on a Citroën (surprise, surprise). It won't return a signal to the
PCM when actuated via diagnostics, and has a stored code reflecting the lack of this return signal in normal use. Runs constantly from a few seconds after startup and does not change speed.
