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.
- 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.
- Remove the door trim upper extension panel. Refer to Trim Panel Replacement - Upper Extension for the appropriate model and model year in SI.
- Remove the door trim panel. Refer to Trim Panel Replacement - Side Front Door for the appropriate model and model year in SI.
- Remove the inside door handle. Refer to Door Handle Replacement - Inside for the appropriate model and model year in SI.
- Remove water deflector. Refer to Water Deflector Replacement - Front Door for the appropriate model and model year in SI.
- Loosen the retaining bolts that hold the window glass to the window regulator assembly. Do NOT remove the bolts.
- 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.
- Disconnect the door electrical harness and set the door interior trim piece aside.
