You need to unclog the drain tubes. Remove the side vent grills, reach in and pull out the bottom of the plastic hoses. Remove the rubber check valves and clean out the debris. This should be done seasonally. Resist the temptation to remove these checks thinking they are not needed. Without them, the fan on high and the van traveling at highway speeds pulls enough air through the tubes backwards that the condensate pan can not drain. The weight of the water filling the tubes will open the valves unless they are hard from age. If they need to be replaced, they are cheap. They are actually the old crankcase breather vent used on Bug engines.

After driving for 4 to 8 hours in hot temperatures, say over 100 deg, our '85 Westi A/C seems to rain water down (or, at least I think it's water -- didn't seem greasy or smell weird). The amount of water seemed to be too much to be explained by condensation as suggested by the VW repair guy. Perhaps this indicates some kind of service or cleaning is in order? Idea's much appreciated, as usual! Thanks, Ivan
