Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Seat Heaters
Heated seat system consists of temperature control switches, circuit breakers, control relays, heating elements, thermostats, and wiring. Seat temperature is selected using control switches and automatically controlled via a thermostat built into each seat cushion heater.
System is powered through fuse No. 4 (7.5-amp) located in driver's underdash fuse/relay box, and fuse No. 3 (20-amp) located in passenger's underdash fuse/relay box. Thermostats monitor seat temperature and will open circuit at a specified temperature. Thermostat closes at less than 93°F (34°C) and opens circuit at about 109°F (43°C). Circuit breakers built into heaters close at less than 86°F (30°C) and opens at greater than 122°F (50°C).
