Lens/Mask Assembly: Removal

Remove instrument panel cluster assembly. Refer to I/P CLUSTER procedure.
Thoroughly clean hands with soap and water to remove any oil or other substances which could damage the cluster. If unable to clean hands, an alternative is to wear surgical gloves during all procedures.
NOTE: It is strongly recommended that rubber gloves (e.g., like surgical gloves) be worn while performing removal and installation procedures to prevent grease, smudges, scratches and fingerprints.
Place Anti-Static Mat SA9502Z down on the work area. In order to ground the mat, connect the alligator clip to a large metal object (e.g., work bench) making sure that the attaching point is a bare metal surface and not painted or coated. Also, put the wrist strap around one of your wrists.
Place a clean, dry, soft material such as a cloth baby diaper on top of the anti-static mat.
Place instrument panel cluster assembly face down on the cloth and the anti- static mat.
With end of housing (white portion of cluster) in one hand and lens/mask assembly (black portion of cluster) in other hand, disengage clip #1 with one hand while separating lens/mask assembly from housing with other hand.
