That should help

Are you interested in a good used switch?

I guess I wonder how you know their God and also OEM. I trusted you on the Mirrors and that came out good

Most thermal engine sensors are open circuited while in your hand. Ohm out the sensor to the case, while heating the sensor, if good ohm meter will show continuity.

At what temperature these off and on events are occurring is another issue.
