147 air cond water leak on passenger carpet
I have been searching for posts on this topic and water on the front passenger floor seems to be a fairly common problem with 147s. I haven't found any documented solutions to the problem so would appreciate any wisdom on this problem. We love driving the 147 but are getting tired of the damp smell and having to dry out the carpet after using the air.
The car is a 2002 147 and the carpet gets wet after driving with the auto air con on for an hour or so. I think there is a blockage in the a/c drain somewhere and it appears to be leaking near where the pipe passes through into the engine compartment at the back of the a/c heater unit. Some water does drip from the a/c drain in the engine compartment when parking the car after a drive, so it is not totally blocked. I have checked for blocked sunroof and wiper area drains and they appear to be flowing freely. The floor gets wet when driving in dry weather so I am fairly certain it is not caused by rain water leaking into the car.
Any thoughts or experiences with fixing this problem are welcomed.
Update: Problem fixed
The condensed water pipe from the air conditoner is very short and horizontal where it comes through the bulkhead into the engine bay. I thought the leak may be due to water coming out of the pipe, running back along the outside of the pipe and then be leaking through the rubber seal and into the cabin. This fitted with where the wettness appeared to be originating. I used some plastic hose to slide over the exit pipe and a right angle joint piece for home garden irrigation so it is turns downwards instead of being horizontal. I used some silicone sealer to seal the connection. Its been 4 weeks now and the carpets have remained dry!
