Replying to: kevlight (Apr 08, 2009 8:23 am) I just pulled out the electrical schematics for the heated seats. There is no timer circuitry or anything like that, which would turn them off. The regular illuminated seat heater switch is to turn them on and off. There are two little unmarked things that look like a mini-switch which is in the seat cushion (two on the passenger seat, two on the drivers seat), which aren't clear what they are. They may be pressure switches, or thermal switches. For instance if it was a pressure switch, perhaps it won't turn on unless someone is sitting in the seat. If it was a thermal switch, it could make connection only when it's cold, and when it heats up it opens up to keep the seat from overheating. I'd take it back to the dealership, they'll fix it for you.

Replying to: kevlight (Apr 08, 2009 8:23 am) These days most seat heaters either have a thermistor for controlling the seat heating level or they have two thermostatic switches. The heating elements get MAXIMUM power only until the desired/designed surface temperature is reached. In the case of the thermostatic switches once the design temperature is reached the system goes into 1/4 power mode and even that will be shut off if the seat surface temperature rises above the temperature setpoint of the second switch. With the thermistor once the design temperature is reached the power is simply switched on and off electronically to hold the seat at the design temperature. The remote starter "feature" is perfectly understandable. I've never owner a car wherein the radio didn't shut off when I turned the ignition completely off, didn't leave it in the accessory position. Charger = power to the cigarette lighter plug...SOP.

Replying to: kiawah (Apr 08, 2009 10:46 am) Thermostatic switches, when the design temperature is reached one of these opens to put the heating element into 1/4 power mode. The second switch has an "overtemp" (discomforting) setpoint and therefore depowers the heater altogether. If/as the seat cools the switch will turn the power will come back on. |

Replying to: wwest (Apr 08, 2009 4:32 pm) Lots of cars have this feature where a lot of the power is available for up to about 10 min. after turning the car off and goes off when a door is opened. You need to brooden your horizens as I had a number of cars with this feature.

Replying to: dmathews3 (Apr 09, 2009 10:33 am) The point is that the window power delay and the headlight delay seem to be the same, turn the ignition off, the power stays on...open the driver's door, power off. Some vehicles have a "like" system but if you open the driver's door first and then turn off the ignition the headlights remain on. |

i've got some deep scratches on my windshield due to my wiper blade not in place. it was raining heavily and i had no choice but to keep it on throughout the night. i haven't talked to my dealership yet. i just wanted to know if there's any reliable DIY scratch removal stuff that anyone ever used? thanks in advance
