There is a thread on the Jag and Denso problem.

We have not responded to this thread since removing the locking pins. Even with the locking pins removed, we experienced random Denso shut down. For IRI we swapped out the jags for victors and the problem has disappeared. The window motors are great without the locking pins and victors. We have no hard data to help with why the Denso's overheat while under very light load with the jags. I think it has something to do with the high switching frequency of the jags interacting with the PTC causing it to self heat. I would like to see First allow the removal of the locking pins. Its easy and improves the performance of the motors. However, The bypassing or removing the PTC is much more questionable. It's an actual modification of the motor. So if you use the window motors, use victors.
