Product description

2018 Cadillac CTS Front Door Water Deflector Right Used OEM 84242131

Description:

Genuine Cadillac OEM Front Right (Passenger Side) Door Water Deflector (part number 84242131). This is a plastic or foam moisture barrier/shield that is mounted inside the door structure, behind the door panel. Its primary function is to prevent water and condensation, which inevitably enters the door shell around the window, from reaching the interior components (like the lock mechanisms, speakers, and electronics) and the inner door panel. Replacement is crucial if the original is torn or missing to prevent water leaks into the cabin. This is the counterpart to the left side deflector (84242132).
