My wifes sebring is starting to act up. The other day she said the car stalled right after starting the car. It started right up and she had no problem after that. Last night, after the car sat for about 1 1/2 hours, she went to go out, and the car would not start at all. No click or anything from the starter. Car would not turn over at all. I checked the battery and it was fine. So i figured it could be the starter or relay. This morning I go to check it out, and it started no problem. Any ideas what it could be.
