Re: Denso Window Motors, Warning - Don't use with Jaguars !
In addition to PTCs automotive motors often have EMC/EMI suppression circuitry intended to keep radios from buzzing etc.

Is it possible that this EMC/EMI suppression circuit that has a resonance with the PWM frequency of the Jaguar?

It could happen that some oscillation is building up due to resonance and the Jaguar is either getting freaked out by it or it is detecting this and shutting down of its own accord.

No data, but a guess at what could be causing this strange behavior.
