Debris in heater box, water under dashboard

[tenchsama]

Hi all,

2009 Toyota Yaris sedan, 76000 miles -

During the summer I began to get a water leak under the passenger side dash when running A/C, sloshing water sound when making turns. Turned out there was a build up of debris (leaves, pine needles) in the heater box. Pinching, blowing out drainage tube no help. Had to have dashboard pulled and box cleaned out ($1000 mostly labor) - not covered by warranty or considered a defect - of course.

Ive heard that Toyota is aware of the problem and there is a replacement cowl (under windshield wiper?) designed to prevent debris from getting into engine compartment/heater box but can't get any information on this...

Has anyone else heard about a replacement cowl?

Any ideas on who to contact - no response from Toyota yet.

Thanks
