A/C - New Remove & Install of Defroster Nozzle Duct
BULLETIN NO.: 96-T-53
ISSUE DATE: October, 1996
GROUP/SEQ. NO.: Body-16
CORPORATION NO.: 681611
SUBJECT:
New Service Procedure for Removal and Installation of Windshield Defroster Nozzle Duct Assembly
MODELS AFFECTED:
1991 - 1997 Saturn Coupes
PURPOSE:
Since 1991, the service procedure for removal of the windshield defroster nozzle duct assembly has required the removal of the instrument panel and
HVAC module. This procedure differed from the Sedan and Wagon procedure due to the sharper windshield angle on the Coupe. Attempting to remove
a windshield defroster nozzle duct assembly from a Coupe, using the Sedan/Wagon procedure, often resulted in the lower attachment tabs on windshield
defroster nozzle duct assembly being damaged. If damaged, the windshield defroster nozzle duct assembly cannot be properly attached to the HVAC
module, and windshield defrosting performance could be affected.
The windshield defroster nozzle duct assembly can be installed from the top without damage, with the instrument panel and HVAC module installed in
the vehicle. Due to the high level of labor required to remove the instrument panel and HVAC module, and the relatively low cost of a new windshield
defroster nozzle duct assembly, a new removal and installation procedure will now be used.
The windshield defroster nozzle duct assembly on the Coupe will be serviced using the Sedan/Wagon procedure, which is currently in the "HVAC
Service Manual," with the installation of a new windshield defroster nozzle duct assembly required. This new procedure will benefit the customer by
reducing the labor cost and vehicle repair time. Coupe windshield defroster nozzle duct assembly labor time will now change due to the new procedure.
The new procedure for replacing the windshield defroster nozzle duct assembly on a Coupe is added to this bulletin for your convenience.
