What would cause my radio not to work sometimes in my 07 Suzuki XL7. When you turn the turn signal on you see the signal light up on the panel but you don't hear the sound of the blinker. This does not happen all the time. It seams like when you go to a destination and turn the car off and get out and start the car to leave the radio and radio diasplay does not come on along with the turn signal sound no working.
