DESCRIPTION
On some vehicles, the front door glass run channel may interfere with the rear door garnish. Since the front door glass
run channel is not fixed strongly enough to the door, repetition of door operation may result in interference and damage
to the rear door rubber seal.
1. When the front door glass is closed, the glass run-channel may be forced to move to the B-pillar side.
2. Under extremely hot climate conditions, the glass run-channel may expand to the B-pillar side.

(3) Front Door Garnish

(2) Rear Door Glass Run-Channel

(4) Rear Door Garnish

To eliminate this concern, the fixing force and durability of the glass run channel against thermal expansion and vibration
has been improved. The shapes of the front and rear glass run channels and the rear garnish lip have been changed to
prevent interference.
Customers experiencing this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE
1. Verify the customer concern.
NOTE:
• Replace the opposite side too, even if there is no damage.
• For this repair, the beltline molding does not need to be removed/replaced, even though the workshop manual
instructs to do so.
2 Adhesive Preparation: Procure an adhesive locally that is suitable for bonding rubber, metal, and plastic (example:
Mazda Seam Sealer, P/N: 0000-77-RPKT-M6).

NOTE: There is no specification for the viscosity of the adhesive as long as it is suitable for the above materials, there is
no restriction on the product.
3. Remove the front and rear door glass run channels and rear garnish according to the instructions on MGSS online. If
side window deflectors are installed, remove them too.

10. Repair the other side doors according to Steps 3 - 9.
11. After the repair is completed, allow the adhesive to cure for 16 hours.
CAUTION:
• Avoid excessive opening and closing of the door until the adhesive has fully cured, as this may cause the
adhesive position to shift.
• If the customer needs to use the vehicle during this period, explain the above precautions to them before
delivering the vehicle.
12. If there are new side window deflectors, install them too (applicable only to vehicles installed with side window
deflectors.)
NOTE: After installing the door glass run-channel, wait for 5 minutes for initial curing before proceeding with the
installation of the side window deflectors.
13. Verify the repair.
