ISSUE:

This TSB article introduces a new procedure for replacing trailer tow mirror glass in the event of mirror glass damage.

ACTION:

Replace the mirror glass. Refer to the following Service Procedure for details.

SERVICE PROCEDURE – MAIN FLAT GLASS AND CONVEX GLASS

MAIN FLAT GLASS/BACKING PLATE ASSEMBLY, LH/RH MANUAL HANDSET AND ELECTRIC VERSION

  1. Detach the scalp from the mirror assembly by unclipping four (4) retaining latches with a 6mm (1/4″) wide screwdriver (Figure 1). The latches are accessible by moving the backing plate/glass assembly to the opposite extreme of travel, manually, to provide an opening for screwdriver access.


    Figure 1 – Article 98-7-7

  2. Remove the scalp from the mirror assembly. Prying the latches open on the scalp at the arm entry openings can also assist with removal (Figure 2).


    Figure 2 – Article 98-7-7

  3. On electrically actuated glass mirror versions, the actuator motors must be detached from the backing plate by unclipping the detachment plate with a screwdriver (Figure 3).


    Figure 3 – Article 98-7-7

  4. Loosen and remove the M6 nut from the backing plate pivot.
  5. Remove the backing plate assembly from the mirror.
  6. Remove the damper pins from the old backing plate and push them back into the original grommet/spring opening from which they came.
  7. If the mirror is non-powered, go to Step 11.
  8. On electric mirrors, remove the detachment plate from the motor jack screws by prying away with a screwdriver seated on the shoulder next to the jack screw ball socket (2 places).
  9. Snap detachment plate into new backing plate.
  10. Re-align the jack screws with the key on the ball socket (Figure 4).

    CAUTION:DO NOT OVERTIGHTEN THE NUTS TO THE BACKING PLATE-TO-MIRROR ASSEMBLY.

  11. Fit the backing plate assembly into the mirror, replace the M6 nut and tighten to 1.4-1.8 N-m (1.0-1.3 lb-ft).
  12. Push the backing plate inward, over the top of each damper pin (manual – 3 places; electric – 2 places) to snap the ball pivot on each into their mating ball socket on the backing plate. On the electric versions, repeat this process to engage the motor jack screws (2 places per mirror).
  13. Check that all ball pivots on the motors and damper pins are engaged.
  14. Replace the scalp, ensuring that the four (4) retention clips are engaged and the arm opening clips are fully engaged.

CONVEX GLASS/RETAINER ASSEMBLY, LH/RH MANUAL HANDSET AND ELECTRIC VERSION

  1. Detach the scalp from the mirror assembly by unclipping four (4) retaining latches with a 6mm (1/4″) wide screwdriver (Figure 5). The latches are accessible by moving the backing plate/glass assembly to the opposite extreme of travel, manually, to provide an opening for screwdriver access.


    Figure 5 – Article 98-7-7

  2. Remove the scalp from the mirror assembly. Prying the latches open on the scalp at the arm entry openings can also assist with removal (Figure 6).


    Figure 6 – Article 98-7-7

  3. Using a pair of needle nose pliers, close the three (3) clips on the convex glass retainer (Figure 7) together and push inward toward the case to be sure they are detached from the mating rectangular holes (hold the slip out of detachment with a thumb while detaching the next clip).

  4. Remove the convex glass and retainer from the mirror.
  5. Replace the new convex mirror assembly into place on the case, ensuring that the clips are located onto the mating rectangular holes.
  6. Push the assembly home until the clips open out and retain the assembly to the case.
  7. Replace the scalp, ensuring that the four (4) retention clips are engaged and the arm opening clips are fully engaged.
