Remy 22056 alternator for the 2006 Chevrolet Trailblazer 6-cylinder 4.2L and other vehicles charges the battery and supplies power to the electrical system while the engine runs. This is a remanufactured unit.
Dimming lights, a battery warning light or a battery that keeps going flat can mean the alternator is no longer charging. Before you replace this alternator, rule out a worn drive belt, corroded battery terminals and a weak battery, since any of them can leave you with a similar no-charge complaint.
The vehicles it fits include the 2006 Chevrolet Trailblazer 6-cylinder 4.2L, the 2006 Chevrolet Trailblazer EXT 6-cylinder 4.2L and the 2006 GMC Envoy 6-cylinder 4.2L. If your vehicle is not one of these, look for it in the "Vehicles it fits" section.
