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.

Make sure the lip on the lower windshield lace sits on top of the air inlet screen panel when installing the air inlet screen.
