Heated Seat Operation

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

When the heated seat switch is placed in the high or low temperature position, battery positive voltage is applied through the heated seat switch signal circuit to the heated seat module. In response to this signal, the heated seat module closes it's contacts and applies battery positive voltage through the heated seat element supply voltage to the heating elements. With the heated seat switch in the high position, battery positive voltage is applied through a 310 ohm resister in the switch and the heated seat high/low signal circuit to the heated seat module. In response to this signal, the module sets the temperature to high heat. When the heated seat switch is placed in the low position, battery positive voltage is applied through a 200 ohm resister in the switch and the heated seat high/low signal circuit to the module. In response to this signal, the module sets the temperature to low heat.
