# WATER LEAK AT VISTA VENT IMPROVE SEALING OF VISTA VENT

#### VEHICLES AFFECTED: 1985-86 'J' AND 'N' SERIES

New vista vent (sunroof) hinges have been released for service on 1985 and 1986 'J' and 'N' models.

The new hinges are available through GM Parts under part no. 20696960. The new hinges are made from hardened steel and are designed to give better performance and deflection characteristics to maintain proper seal to glass contact pressure.

When it is necessary to correct a water leak due to weak hinges or when the vista vent seal is being replaced, it is recommended these new hinges be used.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
