Image Unavailable, Please Login Image Unavailable, Please Login Hi , guys 77 GT4 so assume same Aircon system as 308 series . It works fine I re gassed it before bringing the car to Switzerland.I,ve been competing in a a tough alpine classic car rally and noticed ...... Firstly on tight hairpins ( accent and decent ) a funny fan noise as if the blade were hitting something ...... Secondly actually water tipping out ( after an hour or so ) from under the two centre vents or lateral . We had to place a towel and the radio spontaneously turned on . First day was 300 km of time trails I ended up disconnecting the radio to cut its power . Anyhow after day two the foot well carpets were wet . There is thread on here ...... something about” insulation breaking down “ inside the pan and humid air condensation forming ....something along those lines ?? You have to just live with it . I did run a piece of bush whacker line up the pipe under the front valance , which I assume is the AC drain . That drain drains as well when the car is parked like any other car it does not appear blocked . Do what’s to be done ? Is it a restriction of the main drain ? Does the pan under the dash where the cold matrix sit need a modification? Anybody removed the dash pan ? Any suggestions great fully recommended- except drive on flat roads with the AC off .
