My 2002 Chevy Malibu will not start. After turning the key to "On", the car beeps 6 times. After the last beep, "cal err" appears on the clock/radio display, and the car beeps an additional 4 times (more quickly this time). Also, no lights appear on the dashboard (e.g. check engine light, lights behind speedometer, etc).
Turning the key to "Start" cause the car to try to start (turns over), but it will not. The battery is fine (clock/radio backlight does not dim).
The car worked fine last night.
It might also be worth noting that it rained all day yesterday, and I did have to roll down the window a couple times in the rain (rain got on the window switches).
What could be causing this, and how can I fix it?
