Date: June 02, 2010
Subject: Front Manual Seat(s) Won't Adjust Forward or Rearward, Sticks or Binds (Install Revised Seat Adjuster Bar, Replace Seat Adjuster)
Models:
2004-2010 Chevrolet Colorado

with Seat RPO AM6 or AR9
Condition
Some customers may comment that the front seat(s) appear to be stuck in position and they are unable to move the seat forward or rearward in the
vehicle.
Cause
This condition may be caused by the seat adjuster bar (handle) bending or coming out of position. This may also cause damage to the plastic adjuster
blocks located in the seat adjuster assembly. Seat tracks (adjuster assemblies) that are not parallel to each other may contribute to the development of this
condition.
Correction
Use the following procedure to repair the affected seat(s).
1. Remove the seat from the vehicle. Refer to Front Seat Replacement - Bucket or Split Bench Seat Replacement in SI.
2. Locate the adjuster bar (handle). Determine if the handle pin(s) have come out of the plastic adjuster block(s).
3. If the pin is in the block, inspect the gap between the adjuster bar and the plastic adjuster blocks. There should be no space between the two
components.
4. If the pin(s) are out of the block(s) or there is a gap, the adjuster bar needs to be replaced with the revised part listed below.
