I have a weird issue with my daughter's S70. The car wouldn't start the other day but the radio worked fine. We jumped the car with my van and the car started right up but then we had to input the security code into the radio. Now ever since we did this the headlights no longer work. I've replaced the bulbs thinking maybe we did something when it was jumped but they are still off no matter what button we press :( Any ideas why this would happen?
