Blocked Drains

[ainarssems]

It water condensing from air on the aircon evaporator and it's a lot more then couple of drips.

Take a look under car in hot summer day when aircon has been working for a while standing in one place you might think you have coolant leak. On along journey it could easily be pint of water or more.

Car has pollen filters but some fine dust still get through them and after years of use bacteria and fungi start growing on dust and water until there is enough to block the drains.
