Condition
Some customers may comment that when the A/C is on, they feel moisture on the front floor carpet.
Cause
Example of a Collapsed A/C Drain Grommet
This condition may be caused by a collapsed A/C drain grommet (1), resulting in a wet carpet condition.
Correction
Remove the panels in order to gain access to the A/C drain pass-thru grommet and realign the drain tube using the procedure listed below.
1. Verify the customer condition.
2. Remove the insulator panel (1). Refer to Instrument Panel Insulator Panel Replacement - Left Side in SI.
3. Remove the knee bolster (2).
- Grasp the knee bolster assembly (2) and carefully pull downward to disengage the retaining clips.
Important
When removing the knee bolster, care must be taken not to scratch the steering column cover. This can be achieved by slightly bending the knee bolster to avoid contact with the steering column.
- Disconnect the headlamp switch electrical connector from the headlamp switch.
4. Remove the center console extension panel.
5. Remove the console trim plate (1).
6. Push the carpet down with one hand, and with the other hand, take a pick tool and insert the tool in the grommet.
Important
When installing the HVAC drain tube and grommet, make sure they are properly aligned in order to allow the HVAC water to drain properly.
7. Route the pick around the rubber HVAC drain grommet and make sure the drain tube is properly centered in the grommet. View the figure above and note how the HVAC drain tube grommet is positioned. The lip of drain grommet should be positioned inward of the entire circumference (1).
8. Reinstall all of the panels.
9. Let the vehicle run with the A/C on.
10. Perform a final inspection for the A/C and verify that the system is draining properly.
