Description of operation

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

Heating pads 64FL and 64FR are powered from fuse 20. They are turned on and off with switches (252D and 252Prespectively). The temperature sensor comprises an NTC resistor, the resistance of which varies with the temperature in the heating pad.

Once the heating pads have reached their pre-determined temperature, they are turned off until the temperature has dropped to the lower limit.
