Sequoia Limited 7.5L

Seat heaters have controls for the temperature. ON High the seats do not get very warm. I was told by the dealer this can not be changed. That statement is a lie. The heater is controlled by a power transistor that modulates the voltage to the heater using pulse width modulation technology. There may also be a temperature sensor for limiting the maximum temperature. Any of these items can be used to increase the seat temperature. Why pay for heated seats if they do not get warm?
