Rx 400H Air Conditioning - Rusty Water Discharge

[Pileits]

Anyone else in here noticed rusty colored water discharge from the air conditioner?

Everytime the wife parks her 400h on the nicely painted garage floor the discharge on the floor after the vehicle is parked for a few minutes is all rust colored and stains the floor as well.

The discharge is evident just below the dash board area onto the floor. It is NOT coming from below the engine area.

My guess is something within the air conditioning vapor discharge plumbing is rusting.

Any body else here have something similiar happen. Thanks in advance for the help.

The evaporator is a coated aluminum and the entire HVAC box is plastic.The drain is a formed rubber tube. Depending on where you live it's probably leaves that have made their way into the evaporator box on the blower motor side. Are you using a A/C filter? You should. The fresh inlet is a vertical opening in the fire wall appox. 15" from the passenger side of the car , under the base of the windshield. Servicing any of this requires dash removal . Here in Indiana , I put mesh grills on the fresh inlet to prevent the debris and cridders from entering the evaporator case from the fresh inlet.

@ Mr Horning

Thank you so much for pointing me in the right direction. I will go and check that fresh air inlet opening and see if I can spot any debris.
