The intake of a 929 starting MY 1987 has a thermo switch on top. This sensor
signals to the climate/fan controller box next to the passenger seat that the
intake is very hot. This signal makes the fan controller run the fans at
moderate speed to cool down the engine. It does this when the hood is closed and
ignition is off. It is commonly called "after - cooling" of the engine and
happens when you leave the car. Suddenly you notice the fans kick in to cool
things down a bit.
