I'm going to jump on the bandwagon of replace the battery, but the alternator only if it is bad. It'* true that a bad battery can give the alternator a real work out and may shorten its life, so don't delay too long. Also, as mentioned, the proper battery is a must.

I got a new battery in 2004 it shouldnt be bad thats only 2 years

Anything is possible, how about getting the alternator and battery tested, then let us know if they are both good. We've seen 6 month old batteries go bad from a defect etc.

Let'* do at least those tests and rule the more common items out before trying to diagnose a control module.

Did you get a chance to check the battery connections yet?

I agree. It is the least expensive first corrective action to take.

Did anyone bother to mention that the battery is underneath the seat? :P That'* another nice feature about these cars is that the battery stays nice and clean inside the car.

My bet is on the battery connection. About a month ago, went out to start mine, and nothing. Turns out the cable had literally fallen out of the battery from the corrosion involved. Just grab the cables and see if they are intact and there is nothing leaking.....
