Model and Year: 1989-90 F CAR
TO: ALL CHEVROLET DEALERS
The 1989 and early 1990 F cars may have a "tapping" type noise coming from the rear hatch area. This noise will be worse on rough roads. The noise is coming from the contact assembly in the hatch lid, which is used to supply power to the rear window defogger.
The moveable terminals in the contact assembly if too long, may hit the plastic body of the contact assembly when going over bumps.
A new part was used in production beginning with the following VIN: LL122492
Replace the contact assembly in the hatch with new part number 10098526, following instructions in the Service Manual.
Part is currently available from GMSPO.
