“Wiring connector connected to the radiator fan assembly melted. I had replaced the radiator fan assembly a year earlier to its failure. Upon the repair shop I took my car to calling the dealer, it was mentioned this is a common problem by the dealer. The melting of this connector caused the engine to start over heating and the A/C to no longer cool. Dealer mentioned that the connector is not available and it would take replacing the whole electrical harness. The car only has about 65,000 miles on it.”
