I purchased a used 2001 f150 and noticed that SOMETIMES the lights on the audio controls stay on after I turn off the lights for the vehicle. Does anyone know why. Like I said this doesn't happen all the time and I can't figure out why it does this.

 

I have no Idea..but when I first got my truck I had the stock radio and it would do that too...I would just hit the dash really hard and they would turn off...then I went and bought a new radio
