Water Leak Into Passenger Compartment From Exterior Mirrors (Apply Body Sealer to Exterior Mirror Datum)

Some customers may comment on water leaking through the exterior mirror and tracking behind the door trim and into the passenger compartment.

Water directed onto the exterior mirror may build up inside the mirror until it leaks out of the datum pin hole and into the passenger compartment. This usually happens when a stream of water is directed at the mirror, such as during a heavy rainfall or in a car wash.

The figure above shows water leaking (1) from mirror datum pin (2).

Verify that the water leak is coming from the mirror datum pin. Usually a water mark/trail will be visible by the datum area.

Important: Do not use a sealer that will harden over time.
