Subject: | Heater Blower Inoperative or Water on Passenger Floor (Install Sealing Strip)

Models: | 1999-2001 Oldsmobile Alero

| 1999-2001 Pontiac Grand Am

### Condition

Some customers may comment that water drips on the front passenger floor or that the heater blower is inoperative in cold weather.

### Cause

This condition may be caused by water entering the fresh air inlet to the HVAC case due to poor sealing of the air inlet screen to the fresh air inlet opening.

### Correction

1. Open the hood and remove the windshield wiper arms.
2. Remove the air inlet screen panel and replace the foam seal. Refer to illustration above.
3. Inspect the cowl drain holes located at each end of the cowl. They should be open and free of debris.
4. Reinstall the air inlet screen.
5. Make sure the lip on the lower windshield lace sits on top of the air inlet screen panel when installing the air inlet screen.
6. Reinstall the windshield wiper arms.
