Is the passenger side heated seat supposed to be heated on both the seat part and the backrest part?
It seems like the driver side is on both and the passenger side is not. Since this are my first heated seats, is that how its supposed to be or do I need to get that looked at? |

According to Acura the backrest isn't heated in the passenger-side seat due to the airbag sensors.

| Do you guys know if the heat is supposed to stay on consistently like the driver side or is it supposed to cool down after a certain temperature? On mine, it works normal for about the first 15-20 minutes. Soon after it cools off as if it is switched off. |

| Mine does not cycle off, there may be a thermostat built in to make sure it does not overheat? |

When the 'low' position is selected on the passenger's seat heater switch, power is supplied constantly to a seat cushion heater. The voltage is stepped down via a resistor, and there is no heat regulation.
When the 'high' position is selected, voltage is not stepped down, however it passes first through a thermostat and then a thermo breaker before it supplied to the seat heater. The thermostat cycles on when the temperature at the thermostat is between 98F to 110F. It will turn off when the temperature reaches from 117F to 127F. The thermo breaker is there as a safety, in case the thermostat fails to cutoff the voltage, as shown above. The thermo breaker will cut seat heater voltage when the seat temp reaches 140F to 158F. It will reset when the temperature falls between 95F to 113F. The driver's seat is exactly the same, except voltage is supplied both to a cushion heater, as well as a seat back heater. Note that the thermostat is not designed to regulate a constant temperature output. It either supplies unregulated voltage on or off within a preset temperature range. That's why you may sense the temperature rising and falling, as the thermostat does its job.
Assuming the thermostat is operating within limits, theoretically you could have the seat heater turn on at 98F and off at 127F, a maximum 29F spread. Let's say, however the thermostat is not working, then the thermo breaker is controlling the heater at anywhere between 95F to 158F, a maximum 63F spread.
As an operating technique, I carry the switch in high until the seat reaches a comfortable temperature, then I switch to low, which I find is comfortable for the long run. |

What about the back seats on the /Ent packages? Does the seat backs heat on them?
Thanks

I draw a blank on anything past my 2004 maintenance manual. When you turn the seat heat on, what part of the seat is heated? What does the service manager say? I'm wondering if there is any clue in the owner's manual?
EDIT:
According to the parts list for the L. middle seat, both the cushion and the back portion of the seat is heated. Go here: http://estore.honda.com/epc/asp/rjane007.asp
Enter your zip code, and click on 'parts'. |

In the manual it states that the rear seat heaters heat both the seat and the back.

Are you refering only to the passenger and not the driver side? The driver side get much warmer and stays on constantly compared to the passenger.
