An itch noise coming from the radio/heater control area caused by a related movement between the trimplate and IP skin. | Apply anti-itch at all points of contact.
An itch noise coming from the A-pillar caused by hard contact to the windshield glass and/or IP. | If the trim piece cannot be adjusted properly, apply anti-itch tape in the places of contact.
A rattling noise coming from the passengers foot well area caused by 1 of the following causes:

• | The BCM is loose inside of its mounting bracket.

• | The BCM can be contacting the IP mounting bracket.

If the bracket cannot be tightened, use a foam insulator placed on the PCM in order to provide for a tighter fit.

A rattling noise coming from under the IP area behind the radio caused by the wrong screws used to secure the remote cassette and/or the faceplate is loose. | Secure the faceplate with the correct screws.
An itch noise is coming from the IP area around the cluster caused by the rubber bump stops which isolate the trim plate from the IP are falling off during assembly allowing contact to occur. | Glue on the rubber bump stops and reassemble the cluster trim.
A rattling noise coming from either of the 2 IP edges caused by the end cap is loose at the lower forward corner. There are 2 tabs which sandwich the IP that are not holding the IP tight enough. | Insert the tabs on the end cap into the holes in the IP retainer. Snap the end caps on with the clips to secure.
A rattle at the forward center edge of the IP caused by 1 of the following causes:

• | The acoustic seal may not be properly seated allowing movement of the forward edge of the IP.

• | The IP can be rubbing the windshield.

On Pontiac only, remove the IP and adjust the acoustic seal.

On Oldsmobile only, remove the valance panel and adjust the acoustic seal.

A rattling noise coming from the drivers foot well area caused by the PCM being loose inside of the mounting bracket. | If the bracket cannot be tightened use a foam insulator placed on the PCM in order to provide for a tighter fit.
