First step - check the battery connections and terminals, both at the battery and at the opposite ends of each positive and negative cable. Should be clean and tight, with no corrosion.

Next step, have the alternator and charging system tested, for free - at any local auto part stores. There are several possibilities; battery connections, weak battery, faulty alternator, slipping / worn alternator drive belt - to list only a few.

Try these online resources; www.autopartswarehouse.com, www.rockauto.com, www.partsgeek.com - to list only a few.

In fact, they (RockAuto) list the replacement alternator from around $61.00 (minus core exchange) for your vehicle.

Alternator = REMY part #14720 - or it's equivalent
