On a 2002 Monaco Windsor. This thing is located behind the passenger seat below the overhead cabinet. It looks like some kind of sensor. Does anyone know what it is?
If you remove the white cover, you'll see a single wire (kind of flat on the end)behind it. That's the sensor. Often they were stuck down in the hole and will read more of the wall temp than the room temp. I always pulled them out so that they extended into the cover and then sealed the hole with putty so that they stayed out and would measure room temp and not wall temp.
