Condition
Some customers may comment on a rubbing or scratching noise when the front driver or front passenger power windows are activated.
Cause
The rubber anti-noise sleeve on the window regulator support may wear through, allowing the window regulator to come in contact with the glass.
Correction
Inspect the rubber anti-noise sleeves on the window regulator support. If either or both are worn, damaged or missing, replace both sleeves (front and rear) with new polypropylene sleeves, P/N 19120848. Do NOT replace the entire window regulator assembly.
1. Make sure that the window is closed (glass all the way at the top). Tape the glass to the door header to support the glass.
2. Remove the door trim upper extension panel. Refer to Trim Panel Replacement - Upper Extension for the appropriate model and model year in SI.
3. Remove the door trim panel. Refer to Trim Panel Replacement - Side Front Door for the appropriate model and model year in SI.
4. Remove the inside door handle. Refer to Door Handle Replacement - Inside for the appropriate model and model year in SI.
5. Remove water deflector. Refer to Water Deflector Replacement - Front Door for the appropriate model and model year in SI.
6. Loosen the retaining bolts that hold the window glass to the window regulator assembly. Do NOT remove the bolts.
7. Reconnect the door electrical harness. Use the window switch to lower the regulator so that the window regulator support that the glass rests on is accessible through the access hole.
8. Disconnect the door electrical harness and set the door interior trim piece aside.
9. Inspect the window regulator supports (both front and rear supports).
^ If the rubber anti-noise sleeves are present and NOT damaged or worn, continue with diagnosis of the customer concern. Squeaks may also occur at the cable/pulley assembly, rail, and/or motor and gearbox housing.
^ If the rubber anti-noise sleeves are damaged or missing, replace the sleeves with new polypropylene sleeves, P/N 19120848.
10. Reconnect the door electrical harness. Use the window switch to raise the regulator so that glass support is fully supporting the window glass.
11. Tighten the retaining bolts that hold the window glass to the window regulator assembly.
Tighten
Tighten the bolts to 12 N.m (106 lb in).
12. Install the water deflector. Refer to Water Deflector Replacement - Front Door for the appropriate model and model year in SI.
13. Install the inside door handle. Refer to Door Handle Replacement - Inside for the appropriate model and model year in SI.
14. Install the door trim panel. Refer to Trim Panel Replacement - Side Front Door for the appropriate model and model year in SI.
