ISSUE: Water leaks may occur on the passenger side front floor area. This usually happens during heavy rain, with the car parked nose up or during high blower operation while driving. Water enters the right hand cowl top air vent because of inadequate sealing around the air intake collar.

Figure 1:

ACTION: Install an extension assembly - cowl vent deflector and a screen assembly - cowl vent right hand side. Refer to the following procedure for service details.


1. Open the hood and remove the right and left hand windshield wiper arms.

2. Remove the engine compartment seal from the front edge of the cowl top leaf screen, Figure 1.

Figure 2:

3. Remove ten (10) screws holding the cowl top leaf screens, Figure 2. Carefully position the left hand screen on the windshield out of the way.

NOTE: IT IS NOT NECESSARY TO DISCONNECT THE WASHER HOSES ON THE LEFT HAND SIDE.

4. Remove and throw away the right hand screen.

5. Apply black silicone rubber sealer (D6AZ-19562-BA) to the upper cowl body seam behind the A/C air inlet.
