When I turn on the driver side seat heater **** all the way to on, the seat gets hot but eventually it does not stay on and gets cold, the indicator light on the **** is always on but the seat it not hot anymore

So, I then turn it off then back on and it gets hot again, but again will cut off.

I have a 2008 LS460

What could cause the seat heater cut cut off like this ?

 

Any thoughts on this.

Do we know if the driver seat heater is on a timer ? Mine does not stay on.

Thank you!

 

No timer that I know of, mine stays on until I turn it off.

 

So if mine is shutting off it is obviously broken. What could be the cause ?

(Some of the led's on the actual seat heater **** are burned out, so maybe the switch needs to be replaced) ?

 

Mine cycles
