If everything else has been checked (battery, cables, transmission is in Park, etc.and  the starter motor does not operate at all but the solenoid clicks, the problem is probably in the main solenoid contacts or the starter itself. We offer Bosch and other O.E. factory rebuilt units. Starters are rebuilt to meet rigid factory specifications. When ordering a rebuilt unit, the applicable  core charge is added to your order automatically. This core charge will be refunded in full when we receive your core in a good rebuildable condition. Return freight on the core is the customer's responsibility. (For refund we must receive your core within 30 days)
