The code might be written down in your owners manual, if not you will have to go to the dealer for the code.

There is no blinking red light by the power knob.


take the negative battery terminal off and leave it over night and see if that resets it

Michael Kane

I wouldnt remove the battery cable again since thats what caused the original problem, you just just need the code for the radio and may also have to rescyn the one touch window up/down function.
