SERVICE INFORMATION
If a 1993-96 Altima or 1997 Altima (built before 3/97) exhibits HVAC blower motor noise, the cause may be debris, such as leaves and pine needles,
trapped in the blower motor assembly. Such debris can enter the blower motor through side gaps between the vehicle body and the cowl top panel.
To correct this incident, foam seals must be installed to the underside of the cowl top panel at each end. These foam seals fill the gaps between the
vehicle body and the cowl top panel and prevent debris from entering the HVAC system.
SERVICE PROCEDURE
1.
Remove the windshield wiper arms (two M10 nuts).
2.
Remove the cowl top panel as shown on page BT-21 of the 1996 Altima Service Manual.
3.
Install foam seals A and B to the underside of the drivers side cowl top panel as follows (see Figure 1):
A.
Clean the surface of the cowl top panel where the foam seals will be installed.
B.
Using spray adhesive (3M(R) brand Super 77 P/N 021200-21210 or equivalent) install foam seal B to the underside of the cowl top panel
(see Figure 1).
C.
Remove the self adhesive cover strip and install foam seal A to the underside of the cowl top panel (see Figure 1).
