REPAIR PROCEDURE/INFORMATION
Verify the customer's complaint by playing a commercially purchased CD and/or the radio. Note: It is not advisable to play a burned (home made) CD, due to the fact the recording levels may have been set extremely high, which may cause undesirable chattering, vibration and/or distortion.
1) Check to make sure there is nothing in the door pockets that could cause chattering and/or vibrations. If there is, remove the objects.
2) Remove the door trim (refer to the applicable service manual) and check for loose or missing screws, broken or missing clips. Replace if necessary.
3) Check to make sure that the sealing cover is properly applied (no peeling, no misalignment, no breakage). Repair and/or replace as necessary.
If the speakers still chatter and/or vibrate, perform the following countermeasure(s):
[A] Standard speaker, perform Countermeasure 1 & 2.
[B] High-grade speaker, perform Countermeasure 1.
^ Sealing covers with urethane are used with high-grade speakers; therefore countermeasure 2 does not need to be performed.
How to distinguish between Standard speaker and High-grade speaker
Vehicles equipped with standard speakers use a sealing cover without urethane. Vehicles equipped with high-grade speakers use a sealing cover with urethane.
Countermeasure 1
1) Remove the door trim speaker and sealing cover (see figure 1, below).
2) Apply 3MTM Heavy Drip-Chek(TM) Sealer 08531 to the gap of the seam of the inner door panel (See figure 2, below).
3) Reinstall the sealing cover (if equipped with standard speakers perform countermeasure 2), speaker and door trim.
4) Verify that the chatter and/or vibration is eliminated.
Countermeasure 2
1) Remove the door trim, speaker and sealing cover.
2) Install a new sealing cover using 3MTM Windo-Weld(TM) Round Ribbon Sealer 08625 (See figure 3, below). Make sure to use a uniform bead and press firmly to insure the sealing cover stays in place. Note: Breaks in the bead will allow water leakage and contamination.
^ Reinstall the speaker and door trim.
^ Verify that the chatter and/or vibration is eliminated.
