Water Drain - Air Conditioning Climate Control

[WKwkc]

My C5 2.2HDI EXCLUSIVE Climate Control does not create the usual escape of water from under the vehicle when the AirCon is operating for any period of time. I suspect that it is gathering somewhere in the bulkhead and it is only a matter of time before corrosion sets in. Nothing enters the interior of the car at present.Does anybody have a similar experience.

In the driver's footwell, remove the left plastic lower cover (needs a small torx bit to remove a screw hidden by the cover above it which can be bent up out of the way). The drain rubber pipe, about 10mm diameter, can be seen then coming from the side of the air con evaporator housing. This then goes down and along the side of the tunnel under the carpet about 2 feet before exiting above the long plastic cover under the car. The end of the hose can not be seen without lowering the front of this plastic cover. To see if the hose is clear, pull off the top end and insert a funnel and pour in some water - should then be seen dripping under the car.
