 like you're experiencing where it hasn't worked it's because of a defective battery the voltage falls below a certain point and it just won't work and of course there's other items if you would have a check engine light or any other type of warning lights illuminated on the instrument panel that feature may not work also yeah nothing like that now the rest of the car works fine uh yeah i'll definitely like i said i wasn't aware there was a separate battery for the feature but i'll uh look into that for sure um
