Brakes
The corrosion of the brake booster pump relay connector may cause a resistive short and melt the connector, increasing the risk of a fire.
Corrosion may develop at the brake booster pump connector at the pump relay due to a missing cavity plug. This corrosion can cause excessive heat, resulting in the connector melting and possibly catching on fire. Dealers will apply sealant to the affected connector cavity plugs and re-route the vacuum pump vent hose. If damaged, the front body wiring harness will be replaced as necessary.
