APPLICABLE MODEL(S)/VINS
2019-2020 Mazda3 5-door HB (Japan built) with VINS lower than JM1BP******158118 (produced before November 29,
2019)
DESCRIPTION
Some vehicles may exhibit that the glass run channel of the front door interferes with the rear door garnish.

Since the front door glass run channel is not fixed to the door strongly enough for the following situations, cycles of door
operation may result in interference and lead to damage on the seal rubber at the rear door.
• When the front door glass is closed, the glass run channel may be forced to move to the B pillar side.
• In very hot climates, the glass run channel may expand to the B pillar side.
To eliminate this concern, the following 2 phases have been started as a running change:

• Phase 1
Adhesive has been added between the front door glass run channel and the door panel.
• Phase 2
The shape of the front door glass run channel has been changed so as not to make contact with the rear
garnish.
The shape of the clip at the rear side of the front door glass run channel has been changed for stronger
fixing and the hole at the door panel has been changed accordingly.

Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Replace the front door glass run channels with modified ones, regardless if the other side is damaged or not.
NOTE: Since the clip of the modified front door glass run channel is bigger than the hole at the door panel, cut the clip off
and use a blind rivet instead.
• If the vehicle is NOT equipped with accessory side window deflectors, select Job Type A or B depending on the
damage on the seal rubber at the rear door.
• If the vehicle is equipped with accessory side window deflectors, select Job Type C.
