Hello, my name is***** you for the question. Can you confirm if this is only on the driver seat?

Customer: replied 1 year ago.
it is just the driver seat back

Thank you. In some cases this is due to a failure in the switch itself. Most of the time if this occurs the light will not come on. If the light is blinking then it is usually caused by a failure within the climate control seat module. This is a common failure. I know you said you disconnected and reconnected everything, but did you do this under the passenger seat too? This is where the module is located.

disconnect both of the seat harnesses and reconnect them

If it still does not work then it was not a bad connection. This means you more than likely have a bad module.
